Unfortunately for our peace of mind, there are thousands of instances,
reported by normal people, of exactly this sort of occurrence. We are not
dealing with a purely hypothetical situation.
Such events have been termed traveling clairvoyance, astral projection, or, a
more scientific term, out-of-the-body experiences (OOBEs). We can formally
define an OOBE as an event in which the experiencer (i) seems to perceive
some portion of some environment which could not possibly be perceived
from where his physical body is known to be at the time; and (2) knows at the
time that he is not dreaming or fantasizing. The experiencer seems to
possess his normal consciousness at the time, and even though he may
reason that this cannot be happening, he will feel all his normal critical
faculties to be present, and so knows he is not dreaming. Further, he will not
decide after awakening that this was a dream. How, then, do we understand
this strange phenomenon?
If we look to scientific sources for information about OOBEs we shall find
practically none at all. Scientists have, by and large, simply not paid any
attention to these phenomena. The situation is rather similar to that of the
scientific literature on extrasensory perception (ESP). Phenomena such as
telepathy, clairvoyance, precognition, and psychokinesis are "impossible" in
terms of the current physical world view. Since they can't happen, most
scientists do not bother to read the evidence indicating that they do happen;
hence, not having read the evidence, their belief in the impossibility of such
phenomena is reinforced. This kind of circular reasoning in support of one's
comfortable belief systern is not unique to scientists by any means, but it has
resulted in very little scientific research on ESP or OOBEs.
In spite of the lack of "hard" scientific dfcta, there are still a number of definite
conclusions one can make from reading what material there is.
First, OOBEs are a universal human experience, not in the sense that they
happen to large numbers of people, but in that they have happened all
through recorded history, and there are marked similarities in the experience
among people who are otherwise extremely different in terms of cultural
background. One can find reports of OOBEs by housewives in Kansas which
closely resemble accounts of OOBEs from ancient Egyptian or oriental
sources.
Second, the OOBE is generally a once-in-a-lifetime experience, seemingly
experienced by "accident." Illnesses sometimes bring it about, especially
illnesses which are almost fatal. Great emotional stress sometimes brings it
about. In many cases, it simply happens during sleep without our having any
