frequent OBEs, especially during child-
hood, and even fewer learn to control
them.
People have had OBEs when walking
down the street, sitting quietly, or even
driving a car, and apparently carried
on with what they were doing, but the
vast majority happen when people
are relaxed and lying down. OBEs usu-
ally last only a few seconds or minutes, but in rare cases last for many hours. In
‘parasomatic’ OBEs, people seem to inhabit a second duplicate body outside the
physical one; in ‘asomatic’ OBEs, they are just a disembodied awareness or a point
of consciousness (Green, 1968b; Alvarado and Zingrone, 2015).
OBErs (people who have OBEs) report more psychic experiences and greater belief
in the paranormal than others, as well as better dream recall and more frequent
lucid dreams (Irwin, 1985; Gackenbach and LaBerge, 1988; Blackmore, 2017).
There is no correlation with age, sex, educational level, or religion, nor with stan-
dard personality measures, but OBErs do score higher on measures of hypnotis-
ability, capacity for absorption, and positive schizotypy. The concept of schizotypy
is based on the idea that schizophrenia lies at one end of a continuum running
from normal dissociative and imaginative tendencies to extremely pathological
ones. High schizotypes have lots of unusual experiences, disorganised thoughts,
flat emotion, and unstable mood and behaviour, but more positively they are also
more creative, and there is evidence that OBErs are often ‘healthy schizotypes’
(McCreery and Claridge, 2002), reporting more dissociative experiences and more
hallucinations (De Foe, van Doorn, and Symmons, 2012; Parra, 2010).
OBEs have often been dismissed as pathological dissociation, but although in rare
cases epilepsy and brain damage can lead to OBEs, the majority are not asso-
ciated with any pathology. In one study a group of hospitalised schizophrenics
reported the same frequency of OBEs as a control group (Blackmore, 1996b),
and after studying a very large group of American OBErs, researchers concluded
that their ‘psychological health is generally excellent, ranking with the healthiest
groups in the population’ (Gabbard and Twemlow, 1984, p. 40).
Precipitating factors include relaxation, reduced sensory input, and vestibular
disturbances, as occurs on the verge of sleep. So are OBEs just a special kind of
dream? In surveys, OBErs often say that the world looks as real as or even ‘more
real’ than usual. Some describe OB vision as brighter and clearer than normal,
even claiming a kind of 360 degree vision, but others say it is dim or confusing.
In rare cases, time and space seem to disappear as in mystical experiences. OBEs
can feel somewhat like lucid dreams in that one feels fully conscious and able to
fly around at will, but physiological studies using EEG, heart rate, and other mea-
sures show that OBEs induced in the lab occur in a relaxed waking state similar
to drowsiness, but not in deep sleep and certainly not in REM sleep (Tart, 1968).
OBEs are not easy to induce, although there are lots of popular books describing
how to do it. In the early days of psychical research, hypnosis was used to induce
‘travelling clairvoyance’ or ‘astral projection’, while later experiments tended to
use relaxation and imagery exercises. Some drugs can induce OBEs, especially
the psychedelics LSD, psilocybin, DMT, and mescaline, but none of these provides
