Abduction by aliens or sleep paralysis? - Special Section: The Aliens Files - Cover Story

A Roper Poll claimed that nearly four million Americans have had certain "indicator" experiences and therefore had probably been abducted by aliens. But a study of 126 school children and 224 undergraduates shows knowledge of aliens is related more to watching television than to having the relevant experiences.

If you believe one set of claims, nearly four million Americans have been abducted by aliens. This figure has been widely publicized and is often assumed to mean that millions of people have been visited by members of an alien species and, in some cases, physically taken from their beds, cars, or homes to an alien craft or planet.

Personal accounts of abduction by aliens have increased since the publication of Budd Hopkins's books Missing Time (1981) and Intruders (1987) and Whitley Strieber's Communion (1987). There is considerable variation among the accounts, but many fit a common pattern. Wright (1994) summarized 317 transcripts of hypnosis sessions and interviews from 95 separate cases and concluded, "Numerous entity types have been visiting our planet with some regularity" (Part 2, p. 6). However, the "gray" is clearly the most common alien and over the years a typical account has emerged (see, e.g., Mack 1994; Schnabel 1994; Thompson 1993).

The experience begins most often when the person is at home in bed (Wright 1994) and most often at night (Spanos, Cross, Dickson, and DuBreuil 1993), though sometimes abductions occur from a car or outdoors. There is an intense blue or white light, a buzzing or humming sound, anxiety or fear, and the sense of an unexplained presence. A craft with flashing lights is seen and the person is transported or "floated" into it. Once inside the craft, the person may be subjected to various medical procedures, often involving the removal of eggs or sperm and the implantation of a small object in the nose or elsewhere. Communication with the aliens is usually by telepathy. The abductee feels helpless and is often restrained, or partially or completely paralyzed.

The "gray" is about four feet high, with a slender body and neck, a large head, and huge, black, slanted, almond-shaped eyes. Grays usually have no hair and often only three fingers on each hand. Rarer aliens include green or blue types, the taller fair-haired Nordics, and human types who are sometimes seen working with the grays.

The aliens' purpose in abducting Earthlings varies from benign warnings of impending ecological catastrophe to a vast alien breeding program, necessitating the removal of eggs and sperm from humans in order to produce half-alien, half-human creatures. Some abductees claim to have seen fetuses in special jars, and some claim they were made to play with or care for the half-human children.

Occasionally, people claim to be snatched from public places, with witnesses, or even in groups. This provides the potential for independent corroboration, but physical evidence is extremely rare. A few examples of stained clothing have been brought back; and some of the implants have reportedly been removed from abductees' bodies, but they usually mysteriously disappear (Jacobs 1993).

Theories

How can we explain these experiences? Some abductees recall their experiences spontaneously, but some only "remember" in therapy, support groups, or under hypnosis. We know that memories can be changed and even completely created with hypnosis (Laurence, et al. 1986), peer pressure, and repeated questioning (Loftus 1993). Are "memories" of abduction created this way? Most of Wright's ninety-five abductces were hypnotized and/or interviewed many times. Hopkins is well known for his hypnotic techniques for eliciting abduction reports, and Mack also uses hypnosis. However, there are many reports of conscious recall of abduction without hypnosis or multiple interviews, and the significance of the role of false memory is still not clear.

Another theory is that abductees are mentally ill. This receives little or no support from the literature. Bloecher, Clamar, and Hopkins (1985) found above-average intelligence and no signs of serious pathology among nine abductces, and Parnell (1988) found no evidence of psychopathology among 225 individuals who reported having seen a UFO (although not having been abducted). Most recently, Spanos et al. (1993) compared forty-nine UFO reporters with two control groups and found they were no less intelligent, no more fantasy prone, and no more hypnotizable than the controls. Nor did they show more signs of psychopathology. They did, however, believe more strongly in alien visitations, suggesting that such beliefs allow people to shape ambiguous information, diffuse physical sensations, and vivid imaginings into realistic alien encounters.

Temporal lobe lability has also been implicated. People with relatively labile temporal lobes are more prone to fantasy, and more likely to report mystical and out-of-body experiences, visions, and psychic experiences (Persinger and Makarec 1987). However, Spanos et al. found no difference in a temporal lobe lability scale between their UFO reporters and control groups. Cox (1995) compared a group of twelve British abductees with both a matched control group and a student control group and, again, found no differences on the temporal lobe lability scale. Like Spanos's subjects, the abductces were more often believers in alien visitations than were the controls.
