Out-of-Body Experience

← Encyclopedia

A person lies in bed, or on an operating table, or at the edge of sleep, and the point of view comes loose. They are at the ceiling now, looking down, and the body below — recognizably their own — is no longer where the looking happens. People who report this almost always insist they were awake, and many describe it as more vivid than any dream, which is part of why so many of them conclude that something really left. By the most-cited estimate, roughly one person in ten has the experience at least once, and it recurs more often than it happens singly. It sounds as if it must be either revelation or breakdown. The research record says that in the plain run of cases it is neither.

The out-of-body experience — the term is deliberately colorless, and that is part of its history — names the state in which a person perceives the world from a location outside the physical body, typically an elevated vantage from which the body itself can be seen. Clinicians class it among the autoscopic phenomena and distinguish it from its neighbors: in an autoscopic hallucination one sees a double while remaining firmly in oneself; in heautoscopy it is uncertain which of the two is “me”; in the out-of-body experience proper, the self has unambiguously relocated. Celia Green, who collected some four hundred first-hand accounts in 1968 and built the first taxonomy, treated it as an anomalous perceptual experience and left the larger question open. The accompanying sensations are consistent across collections: floating, falling, a slipping-out at the verge of sleep, tingling, buzzing in the head, and, in about half of the sleep-onset cases, the locked-muscle feeling of sleep paralysis. Even the famous silver cord joining body and double turns out to depend on where the accounts were gathered. Robert Crookall, drawing his cases from spiritualist newspapers, found the cord everywhere; in Green’s less selected sample, fewer than one report in twenty-five mentioned anything of the kind, and most experients described being a disembodied awareness with no second body at all.

The experience is far older than its name. Western esotericism called it astral projection: a deliberate excursion in a subtle vehicle — the body of light of Hermetic and Neoplatonic lineage — through an astral plane lying between Earth and the heavens. The phrase itself was coined and promoted by nineteenth-century Theosophists, who took the idea of the astral from the French occultist Éliphas Lévi and developed it. Victorian spiritualists spoke of travelling clairvoyance; Frederic Myers preferred “psychical excursion”; the Hermetic Order of the Golden Dawn taught a named technique for going out in the Body of Light. Sylvan Muldoon and Hereward Carrington’s The Projection of the Astral Body (1929) gave the practice its modern manual, elastic cord included. The neutral term arrived in 1943, when G. N. M. Tyrrell introduced “out-of-body experience” in Apparitions — a researcher’s word, adopted by Green and others precisely because it did not decide in advance what the experience was. Robert Monroe’s Journeys Out of the Body (1971) then carried that neutral term to a mass audience of about a million readers, and an institute, a training program, and — as a matter of documented Cold-War record — visiting military officers followed.

The states in which the experience arises make a long and mostly ordinary list: drowsiness and sleep onset, sleep paralysis, migraine, extreme fatigue, sensory deprivation, epilepsy, general anesthesia, dissociative drugs, the near-death context, and deliberate cultivation by practiced individuals. None of this implies illness; most people who report one are psychologically healthy, and a study of a hundred epilepsy patients found nothing in the profiles of the seven with seizure-associated experiences to set them apart. Nelson and colleagues reported in 2007 that experients are more likely to have sleep paralysis, tying the phenomenon to REM intrusion — fragments of the dreaming state breaking through into waking arousal.

Then the laboratory got a handle on it. In 2002 Olaf Blanke and colleagues, mapping the brain of a patient being evaluated for epilepsy surgery, found that electrical stimulation of the right angular gyrus — at the junction of the temporal and parietal lobes — induced an out-of-body experience, repeatedly and on demand. The same site also produced illusory transformations of the limbs and a sense of whole-body displacement, which pointed at a mechanism: a failure to knit the body’s touch, position, and balance signals together at that junction. Five years later, two studies in Science showed that the experience needs no electrode and no patient. Henrik Ehrsson, and separately Bigna Lenggenhager working with Blanke, fitted healthy volunteers with head-mounted displays showing their own bodies from behind and touched them in synchrony with what they saw; the volunteers’ sense of where they were drifted out of their bodies, toward the camera’s vantage or toward a virtual body seen ahead of them. Blanke’s 2012 synthesis drew the arc together: the sense of being someone, somewhere, looking out from here is assembled from visual, somatosensory, and vestibular signals, and when those signals conflict, the assembly comes apart into exactly the three pieces an experient describes — whose body, where I am, and where I see from.

The literal claim — that something actually leaves and actually sees — admits a clean test: place information where only a detached observer could read it. The tests have been run. In 1968 Charles Tart had a subject known as Miss Z sleep four nights in his laboratory under EEG, with a five-digit number on a shelf above the bed; on the fourth night she reported it correctly. The experiment, documented today largely through later accounts and the critiques attached to them, is not accepted as evidence: the subject was not searched or continuously watched, Tart acknowledged dozing, the number could plausibly have been read in the reflection of a wall clock, and Susan Blackmore observed that the EEG showed the interference expected from physical movement. It was never repeated. Karlis Osis’s trials in the 1970s with the psychic Alex Tanous yielded 114 hits in 197 attempts at remote targets — but roughly 108 were expected by chance, and Blackmore concluded the work offered “no evidence for accurate perception in the OBE.” In the AWARE study of cardiac-arrest survivors (2014), ceiling-facing shelf targets installed for exactly this purpose went unidentified, and only about two percent of survivors reported the explicit seeing-and-hearing form at all; the one verifiable-awareness case arose in a room where no target had been placed. Those who hold the survivalist reading — that consciousness genuinely travels, in an astral vehicle or otherwise — continue to hold it, as their claim; the shelves, so far, have gone unread.

What to make of this is interpretation, and the interpretation here is the site’s. For most of recorded history the out-of-body experience lived inside vocabularies that already contained its explanation — astral projection, the body of light, travelling clairvoyance. When the experience was finally carried into the laboratory, what the laboratory found was not a vehicle but a model: the brain’s continuously updated answer to the questions of whose body this is, where the self sits, and from what point it looks out — an answer that an electrode or a well-arranged sensory conflict can visibly revise. That settles less than either side tends to announce. The induction results explain how the vantage can move; they do not, by themselves, adjudicate every claim ever made from it. What they do establish is strange enough on its own: the place a person seems to be standing is something the brain decides, and the decision can be changed — convincingly, from the inside, while the body lies still.
