3. Characteristics of Apparitions
In looking at the various types of apparitions in the previous section, we also got a brief look at some of their characteristics. In this section, we provide a fuller summary of their characteristics, based on previous findings in parapsychology and psychical research (Irwin, 1994, Sect. 8; Roll, 1982, Sect. 2; Tyrrell, 1953/1961, Apparitions, Ch. 2).
The first characteristic naturally deals with physical appearance. Unlike the misty and translucent ghost of classic folklore, many apparitions are described by witnesses as being solid looking and life-like. For example in the "Morton Ghost" case, in which the Despard family repeatedly saw the figure of a spectral widow over the course of several years, Rosina Despard had stated that the figure "...was so solid and life-like that it was often mistaken for a real person" (Morton, 1892, p. 321).3 In a similar fashion, we saw in the crisis case (Section 2) that the woman and her daughter initially took the apparition to be the woman's real father. In the bystander case, the doctor described the image of his late father-in-law as being opaque and life-like.
While appearing solid, some apparitions can apparently exhibit physical or non-physical features. For instance, some appear to cast shadows and reflections. One curious example of an apparition casting a reflection is seen in one woman's personal account of a crisis case, which Feather and Schmicker (2005) present in their book The Gift:
"My mother lived in California and I lived in Wichita, Kansas. At 9:40 A.M. on February 17, I was sitting in my bedroom at my dressing room table, brushing my hair in front of the mirror. Suddenly the room was illuminated with the strangest light, one I can't fully describe. I then felt a rustle of wind across my shoulders, and a faint sound like the brushing of birds' wings. Then I looked in the mirror.
"My mother was standing behind my chair ... She just stood and smiled at me for a full thirty seconds. I finally said, 'Mom!' and rushed for her, but she disappeared, light and all. I was so upset by this that I shook for an hour. When my husband came home for lunch, I told him about it and got myself ready for a phone call that mother was dead ... Sure enough, about one P.M. that same day, the call came that my mother was gone ..." (pp. 261 – 262).
In other cases, apparitions have been seen to appear or disappear in enclosed rooms, and pass through doors and walls (Stevenson, 1982, p. 353; Tyrrell, 1953/1961, pp. 56 – 58). Attempts to touch an apparition have either resulted in the figure apparently eluding the hand to where it is unable to be touched, or the hands or arms simply passing through the figure. An example in which the apparition eludes the witness' hand can be found in the Morton Ghost case, in which Rosina Despard describes her attempts to touch the spectral widow. She noted that, "It was not that there was nothing there to touch, but that she always seemed to be beyond me, and if followed into a corner, simply disappeared" (p. 315). This latter statement may be valuable, in that it offers the hint that any non-physical features of an apparition may perhaps relate to distortions in perception on the part of the witness. If this is so, then it may suggest that, despite looking physical, apparitions may be mental forms, as well. That is, how the witness perceives the apparition may be partly determined by his or her own mental state at the time.
Although they traditionally represent deceased persons, we see in some cases that apparitions can also sometimes represent people who are still living. An example comes from an account given in a study of cases by Dr. Louisa Rhine (1957):
A little old lady came around every Thursday morning selling eggs from door to door and she always stopped at my house. This Thursday I had to go to town and as I was coming up the little road leading to my house I saw the egg lady standing on the porch. I noted that she was wearing a new pink dress and a sort of little bonnet to match. Just as I spied her, she turned to step off the porch and called to her to wait and then she just disappeared.
She never came out my gate, she didn't go anywhere, she just wasn't there. I was not more than 50 feet away when I first saw her and there were no bushes or plants to obstruct my vision. Later in the afternoon a knock sounded on my door and when I responded there stood the little egg lady dressed in pink and with her basket on her arm. I told her I was sorry I was not at home when she called about an hour earlier. She looked very surprised but smiled as she answered, "But this is the first time I have been here today. An hour ago I was just leaving the ranch. I was thinking about you and wondering if you wanted some eggs" (p. 22).
In addition, apparitions of the living may sometimes occur in crisis cases, when the person whose apparition is seen is ill or in an accident, but not faced with the threat of death. We shall also see in the next blog post that there have been a few rare cases in which living people have attempted to intentionally make themselves appear as an apparition to people they know.
Some apparitions may seem to exhibit behavior that suggests that they have some degree of awareness of their surroundings (Tyrrell, 1953/1961, pp. 60 – 66). Dr. Harvey Irwin (1994) offers the illustrative example that if a witness "... moves around the room the apparition's head may be said to have turned to follow these movements" (p. 58). Another interesting example comes from an account by Rosina Despard of an encounter with the spectral widow:
[The widow] crossed the drawing room, and took up her usual position behind the couch in the bow window. My father came in soon after, and I told him she was there. He could not see the figure, but went to where I showed him she was. She then swiftly went round behind him, across the room, out the door, and along the hall, disappearing as usual near the garden door, we both following her (Morton, 1892, p. 317, emphasis added).
This account suggests that, rather than simply passing through him, the spectral widow had moved to intentionally avoid Rosina's father as she exited the room. Rosina additionally noted that the widow would always move to avoid the light, leaving the witnesses unable to tell if she cast a shadow (p. 321). Apparent displays of awareness such as these tie into the issue of whether or not some apparitions are intelligent, an issue we shall discuss a bit more in Section 7.
Although the majority of apparitions have been witnessed by one person, there have been a small number of cases in which an apparition was collectively perceived by more than one witness. As we saw in the crisis and post-mortem cases (Section 2), two individuals may perceive the same apparition at one time. On the other hand, one witness may see the apparition, while another may not; this was apparently the case in the account by Rosina Despard involving her and her father, above.
Some apparitions of the dead tend to be seen in the geographical location where they once lived or worked (as in haunting cases), or around people who knew them in life (as in bystander-type cases). In addition to the Gordy case (Section 2), another example comes from Dianne Arcangel (2005, pp. 18 – 20), who relates a personal account of the experiences that workers at her family's dry cleaning business have had with the ghost of a man named Dyer. Employed with the business for about 30 years, Dyer worked diligently at his spotting board from morning till night, until his sudden death from a heart attack. Not long after, a female co-worker walked in and saw Dyer working behind his spotting board. She smiled and waved at him, and he waved back. The woman turned to put her things down, and when she turned back to him, Dyer was gone. Several other workers who were employed there later on reported similar incidents, and tenants of the apartment that was later built above the business by Arcangel's husband also reported seeing the spectral figure of a man resembling Dyer. Her husband noticed that one particular area of the apartment, located directly over the area of Dyer's spotting board, was constantly cold, even in the summer months. Arcangel says that neither her husband, the later workers, nor the tenants had ever known about Dyer prior to the experiences.
A comparison of four separate survey studies, shown in Table 1, suggests that more (non-haunting) apparitions tend to be of people with close family relation to the witnesses, rather than strangers.4
Table 1. Relationship Between the Apparition and the Witness in Apparition Cases (% Cases)
Values not cited are marked with a dash (-). All values are rounded to the nearest one percent.
In a later survey study, Dr. Haraldsson (1994) stated that nearly half of the figures seen in the 357 apparition cases he gathered were of a relative of the witness. In contrast, 29% of those cases involved the witness seeing the figure of a person unfamiliar to them. Similarly, in reviewing studies that compared apparitions of the dead with those of the living, Dr. Ian Stevenson (1982) had noted that: "No fewer than 78% of apparitions of the dead were perceived by a [witness] to whom the [deceased person] had had strong emotional ties, such as a husband, wife, or fiancé; and among apparitions of the living the percentage of such appearances rose even higher, to 92%" (p. 351).
There is some indication that the farther one gets from a person's time of death, the less frequently that person's apparition appears. In other words, sightings of the apparition of a deceased person tend to decline in frequency with increased time from the person's moment of death. Evidence for this initially surfaced in the late 1880s, when two prominent psychical researchers, Edmund Gurney and Frederic Myers (1888-89), had conducted a survey of early apparition cases they had gathered and published in a two-volume case anthology of psychic experiences entitled Phantasms of the Living (Gurney, Myers, & Podmore, 1886). They observed from these 211 cases that "... the recognised apparitions decrease rapidly in the few days after death, then more slowly; and after about a year's time they become so sporadic that we can no longer include them in a steadily descending line" (Gurney & Myers, 1888-89, p. 427). A similar decline in apparitional sightings was observed by Rosina Despard in the Morton Ghost case. She noted that from 1882 to 1884 she saw the spectral widow "... about half a dozen times" (Morton, 1892, p. 314), and it was also seen by several other members of her family during that time period. It was reportedly seen frequently throughout the year of 1885 (p. 318). By 1887, Rosina noted that "... we have few records; the appearances were less frequent" (p. 321). She added that from 1887 to 1889, the spectral widow was rarely seen, and then: "From 1889 to the present, so far as I know, the figure has not been seen at all" (p. 321).
The appearance of an apparition can sometimes be accompanied by certain kinds of subjective effects, such as feeling sensations of cold, wind, or touch. In the survey of apparition cases described in his classic book Apparitions, psychical researcher G. N. M. Tyrrell (1953/1961) observed that the experience of cold breezes and similar cooling sensations was fairly frequent across witness accounts. For instance, some witnesses gave the following statements: "I ... felt myself grow perfectly cold"; "A cold, shivering feeling came over me"; "The apparition 'laid a cold hand on his cheek'"; "As if a cool wind was blowing about me" (p. 73). Rosina Despard stated that similar cold sensations were sometimes felt in proximity to the spectral widow of the Morton Ghost case (Morton, 1892, p. 325).5
One final characteristic of apparitions is that, aside from being visual, some can be purely auditory, seeming to manifest as sounds reflective of human activity. An example of an auditory apparitional experience can be found in an investigation by Dr. William Roll (1991) of the alleged haunting phenomena witnessed by the tour staff and crew of the Queen Mary cruise ship, now permanently docked in Long Beach, CA. According to accounts by the staff and crew, sounds of loud metal impacts, voices, and rushing water are sometimes heard coming from the lower forward compartments near the ship's bow. However, when the compartments are checked, no one is found to be in the area, nor is there any sign of damage or a leak. To see if these sounds might represent an objective event rather than being purely subjective, Roll attempted to record them by leaving a voice-activated tape recorder overnight in the bow. When retrieved in the morning and played back, it was discovered that "... the tape recorder picked up a strange sequence of noises. You could hear heavy blows of metal, sounds of rushing water and voices, one of which, low pitched and gravelly, was almost intelligible" (p. 58). The recorded sounds were found to be strikingly similar to a description given by the ship's chief engineer, who heard the sounds on several occasions when he was in the bow area with no one else around. In addition, the nature of the sounds seemed consistent with a tragic event occurring early in the Queen Mary's sailing history, when it had been a military transport during World War II. During an evasion maneuver off the coast of Scotland in October of 1942, the bow of Queen Mary had accidentally collided with the British battle cruiser Curaçoa, tearing the smaller cruiser in half and resulting in the deaths of over 300 British sailors.6
Dr. Erlendur Haraldsson (1994) offers another example of an auditory apparition in his second survey of cases, which again seems to reflect the activity of a person:
Shortly after our father died, I came to his house with my brother. We knew that there was nobody in the house, and then we heard the old man at his desk. He was walking around, opened the door, and closed it again. Both of us stopped and listened when we entered, and then I remarked: "I guess there is no doubt who is up there." "No, there is no doubt about it," my brother replied. Both of us went upstairs; no one was there. We had heard this so clearly. He was 85 years old when he died, and he walked slowly, you know, had the typical old man's way of walking (p. 3).

3.) The "Morton Ghost" case, documented by 19-year-old medical student Rosina Despard, is a classic in psychical research in that offers another good example of a haunting apparition. We previously alluded to this case in our second primer (Williams, Ventola, & Wilson, 2008), and refer the reader to that primer for a brief and convenient summary.
4.) Aside from the data of Persinger (1974) and Haraldsson (1988-1989), the results shown in Table 1 were calculated from data presented in Appendix Table 2 of Osis and Haraldsson (1977, p. 218), and the Appendix of Arcangel (2005, p. 284, 291). Cases in which the apparition was of a spiritual, historic, or unidentifiable figure are excluded.
5.) For additional discussion of cold sensations in relation to apparitions and haunt phenomena, see our second primer.
6.) In the late 1980s, Unsolved Mysteries had aired a segment on the alleged haunting of the Queen Mary and the investigation of it by Roll and British psychical researcher Tony Cornell. A two-part streaming video clip of this segment can be found on YouTube – Part 1 and Part 2. A sample of Roll's recording of the unusual sounds in the bow area can be heard in Part 2.
Part 2. Types of Apparitions
Although the two terms are often used synonymously, it is useful to initially define what we mean by “apparition.” The term apparition, from the Latin word apparere (meaning “to show oneself”), may be formally defined as:
An experience, usually visual but sometimes in other sense-modalities, in which there appears to be present a person or animal (deceased or living) ... who/which is in fact out of the sensory range of the [witness]” (Thalbourne, 2003).
In other words, it is the experience of the presence of a person or animal – living or dead – that is not actually there, which seems to occur primarily through sight, but at times can seem to occur through the other senses (sound, smell, taste, and touch). This term is a bit broader than the more popular term ghost (from the German word geist for “mind” or “spirit”), which refers to the apparition of a deceased person, usually in connection with a haunting. Although we will use both terms throughout this primer, we shall primarily use the term apparition, given its broader meaning.
There are actually several known types of apparitions that have been documented by psychical researchers and parapsychologists since the late 19th century.1 They include: crisis apparitions, post-mortem apparitions, deathbed visions, haunting apparitions, and apparitions of the bystander-type. In addition to describing each one below, we provide an illustrative case example of each to help the reader better grasp what each entails.
Crisis: As implied by its name, a crisis apparition appears to a witness at a time when the person whose apparition is seen is experiencing a state of crisis, whether it is an accident, an illness, or even the threat of death. A good example of a crisis apparition case is given by Dr. Sally Rhine Feather and author Michael Schmicker (2005) in their book The Gift:
A woman and her fifteen-year-old daughter had recently moved to California from their previous home in Washington D.C., where they had left the woman’s father very ill. One day not long after moving, they entered the dining room, and to the woman’s great surprise, there stood her father. “Why Dad, when did you get here?” she exclaimed.
At that point, her daughter turned around to look, and she, too, saw the figure of her grandfather, his hand upraised in a gesture of greeting or perhaps blessing, but he slowly faded away, and they both suddenly realized that he was not really in California in their house. Shortly afterward, they received the news that he had died (p. 254).
In addition to representing a crisis apparition, this case has three other interesting aspects to it. First, it is case where the apparition was collectively perceived, meaning that it was witnessed by more than one person. Second, the apparition was apparently so real looking to the woman that she actually mistook it for her real father at first. This goes against the folklore-based view that apparitions are often only misty, translucent outlines. Third, the apparition of the man seemed to acknowledge the presence of his daughter and granddaughter, suggesting that it had some degree of intelligent awareness. We shall discuss these aspects a bit more in future installments of this primer.
Post-mortem: As implied by its name, a post-mortem apparition appears after a person’s death, anywhere from several hours to several years after. As an example, we briefly recount a case documented by survival researcher Dianne Arcangel (2005, pp. 70 – 72):
About four months after her son Tommy had been tragically murdered, a woman was out walking Tommy’s dog in the daytime and they were passing by the parking lot where Tommy had kept his Jeep when the dog began barking and pulling on the leash. Looking up, the woman saw a young man standing in a blue outfit about 30 feet away, although she could not see him clearly because she was not wearing her glasses. When finally put them on, she recognized Tommy standing there on the sidewalk and smiling at her, wearing a blue outfit he had bought but never got to wear before he died. She immediately called out to him, and she and the dog began running toward him. But then, the image of Tommy seemed to slowly turn around and glide away, his feet being about an inch off the pavement. Despite how fast they ran, the woman and the dog could not catch up to him, even after pursuing him for three blocks. Then, the woman’s sight of her son was abruptly obstructed by some passing schoolgirls, and when she looked up again, the figure of Tommy was gone.
This case has two other interesting aspects to it. Similar to the crisis case, the apparition in this case was apparently witnessed not only by the woman, but also by the dog. It also seemed to suggest an optical effect, as the woman needed her glasses to see the apparition clearly.
Deathbed Vision: Near the moment of death, some terminally ill and dying patients have described seeing images of people and places that seem to relate to an afterlife existence, images known as deathbed visions. Reports of such visions have been recorded since the 19th century (Rogo, 1978), and are still occasionally reported today among healthcare and hospice workers (e.g., Arcangel, 2005, pp. 110, 116 – 120).
Among the images described by patients are apparitions of deceased friends and relatives. In the 1970s, Drs. Karlis Osis and Erlendur Haraldsson (1977) had surveyed and interviewed 877 medical doctors and nurses in India and the United States, whose patients had reported seeing deathbed apparitions. In one of the 418 cases they documented, a nurse recounts the deathbed vision related to her by an intelligent 76-year-old female patient who had suffered a heart attack:
[The patient’s] consciousness was very, very clear – no sedation, no hallucinogenic history. She was cheerful and confident that she would recover and return to her daughter who badly needed her at home. Suddenly she stretched out her arms and, smiling, called out to me. “Can’t you see Charlie [her dead husband] there with outstretched arms? I’m wondering why I haven’t ‘gone home’ before.” Describing the vision she said, “What a beautiful place with all the flowers and music. Don’t you hear it? Oh, girls, don’t you see Charlie?” She said he was waiting for her. I feel she definitely saw her husband (pp. 80 – 81).
During her experience, the woman had a feeling of peace and serenity reportedly come over her. She remained oriented to her surroundings, and was able to talk with the nurse and the family at her bedside during the vision.
This case has two aspects to it that are consistent with other cases of deathbed visions. First, as indicated in the narrative, the woman was not medicated or sedated at the time of her vision, indicating that it was not a drug-induced hallucination. Similarly, most of the patients in other cases were not found to be medicated, sedated, running a high fever, or in a delirium at the time of their vision (Osis, 1975; Osis & Haraldsson, 1977, pp. 70 – 73), arguing against a medical-related hallucination as the cause for their vision. Second, the apparition seen by the woman was that of a close relative (her husband). Similarly, a majority of the patients (90%) in other cases had seen close relatives (Osis & Haraldsson, 1977, p. 64). We’ll return to this second finding in the next installment.
Many patients regard the deathbed apparitions they see as “take-away” figures, meaning that the apparition seemed to appear for the purpose of greeting, inviting, or leading the patient to the afterlife. This apparent purpose of the apparition was noted in nearly two-thirds (65%) of the cases documented by Osis and Haraldsson (1977, pp. 65 – 67). Reflecting on her experience as a hospice chaplain, Dianne Arcangel (2005) openly states: “I have never sat with a dying patient who was not in the accompaniment of an apparition as their time grew near. No one ever dies alone” (p. 120, her italics).
Haunting: As many paranormal enthusiasts are probably all too aware, most of the apparitions seen at allegedly haunted sites do not take the form of the classic ghost of folklore, instead appearing as shadowy forms, floating lights, and hazy mist-like clouds. It seems that, in most cases, these kinds of apparitions are more likely to have a geophysical and/or psychological explanation (for reviews, see Persinger, 1974, Pt. II; Persinger & Koren, 2001; Roll & Persinger, 2001), and are less likely to be indicators of survival. However, there have been a few rare cases in which apparently well-defined apparitions of deceased human individuals have been repeatedly seen over time in the places where they once lived or worked. One such case is the “Gordy” case, initially investigated in the late 1980s by Dr. William Roll (in Roll & Persinger, 2001, p. 160), which we briefly summarize here:
Soon after moving to a new home with her family, a little girl named Heidi Wyrick had met a man in her neighborhood named “Con,” who invited her to play on a swing. When Heidi asked for permission to do so, her mother asked about Con and Heidi described him as “having blood all over.” Concerned that Con may be a kidnapper or a child molester, Heidi’s parents had the neighborhood searched for the man, but were unable to find him. A short time later, Heidi began speaking of regularly meeting with another man in the neighborhood named “Mr. Gordy” to play on the swing, and her parents figure that Con and Mr. Gordy are the girl’s imaginary playmates. Eventually they discover that an elderly gentleman named James Gordy, as well as a man named “Lon,” had actually lived in the neighborhood many years back, and that Lon had lost his hand in a machinery accident. The descriptions that Heidi gave of the two men were later found to closely match photographs of them (she was also able to correctly pick them out of a random collection of old photos), and Roll could find no normal way in which Heidi could have learned about them prior to her family’s discovery of their identities.2
The Gordy case seems to contain a possible parapsychological component, in that it suggests that Heidi was able to somehow psychically perceive the apparitions of people who had once lived in her local surroundings. How might we come to better understand this? We’ll briefly look at some possible theories in a later installment of this primer.
Bystander-Type: It turns out that apparitions may not only be associated with a haunted location; in rare cases, they may be associated with a person. Rather than being seen in the place where they once lived or worked, some apparitions have been witnessed in close proximity to people who once knew them in life. Dr. Louisa Rhine (1957) had coined the term bystander-type case to label these kinds of cases, noting that, “...these cases are suggestive of the haunting cases, the main difference, however, being that in these the link is a person rather than a geographical location” (p. 39).
An example of an apparition of the bystander-type comes from a study by the late Dr. Ian Stevenson (1995), in which he had interviewed a medical doctor who had once witnessed such apparition while keeping vigil at the bedside of his mother-in-law, who was very ill, in a coma, and near death. According to the doctor:
I was standing by her bed and no one else was in the room. She had an agonal inspiration, and at that moment I had a very clear picture of G. C. [her late husband] standing across from me with his arms outstretched, and he said, “Flora, I’ve been waiting for you.”
I did not really have to look to see that my mother-in-law had died, but the physician in me pushed me to verify that (p. 362).
The doctor stated that the figure he saw of his late father-in-law was “...quite opaque, as he would have seen him in life” (p. 362). He was only able to see the figure from the waist up, but believed that the surrounding furniture had blocked his vision of the rest. Prior to his encounter, the doctor believed that he had only been able to see his father-in-law only once or twice while his father-in-law was still alive, but he was familiar with his father-in-law’s appearance from family photos. However, he had not expected to see his father-in-law at the time of his mother-in-law’s passing, stating that, “I was surprised but comforted by what I saw” (p. 363).
In this case, the doctor was able to see the apparition of a man in close proximity to the man’s dying wife, and thus the doctor was acting as a third person “bystander” witness (hence the term). One might notice that this case seems similar to a deathbed vision, but we should point out that it cannot be classified as one in the strictest sense because the mother-in-law was comatose and did not herself perceive the apparition of her deceased husband.
The case has three other interesting aspects to it. First, as in the crisis case, the apparition that the doctor saw appeared solid. Second, as in the deathbed case, the apparition he saw was of a relative in his family. Third, the doctor reportedly heard the apparition speak, suggesting it had some degree of intelligence. We’ll look more at these aspects in future installments.
1.) For some readers unfamiliar with the history of parapsychology, the distinction between “psychical research” and “parapsychology” may be a bit unclear. Parapsychology actually owes its roots to psychical research, which began in 1882 when a group of scholars associated with Cambridge University in England had formed the Society for Psychical Research, which was devoted to the serious study of various psychic phenomena, including telepathy, clairvoyance, psychometry, mediumship, and hauntings. Parapsychology arrived on the scene in the 1930s when Dr. J. B. Rhine and his colleagues had formed the Duke University Parapsychology Laboratory in order to study psychic phenomena via controlled experimental work. A few recent books offering some accessible overviews of the history of parapsychology and psychical research for the interested reader are those by Dr. John Beloff (1993), Deborah Blum (2006), and Stacy Horn (2009). In addition, a useful list of additional print and Internet sources has recently been compiled by Dr. Carlos Alvarado (2009).
2.) In the early 1990s, the popular television show Unsolved Mysteries had aired a segment that profiled this case and Roll’s investigation of it. A two-part streaming video clip of this segment can be found on YouTube – Part 1 and Part 2.
