How can the OBE be explained?
Most theories of the OBE either claim that something leaves the physical
body, or that it does not. Then within these two major categories there are
several different types of explanation, and there is perhaps a last possibility;
that any such distinction is meaningless and artificial. The theories can
be divided up as follows [Bla82]:
A.
Something leaves the body.
1. Physical theories
2. Physical astral world theory
3. Mental astral world theory
B.
Nothing leaves the body

Something Leaves the Body
Physical Theories
(a physical double travels in the physical world)"
First there is the kind of explanation which suggests that we each have a
second physical body which can separate from the usual one. There are two
aspects to consider, one being the status and nature of the double which
travels, and the other being the status and nature of the world in which
it travels. In this theory both are material and interact with the normal
physical world. You may immediately dismiss this notion, saying that the
double is non-physical.
To
make this theory even worth considering it is
necessary to assume that this double is composed
of some 'finer' or more subtle material that
is invisible to the untrained eye. This kind
of idea is sometimes expressed in occult writings.
The idea appears, for example, as the 'etheric
body' of the Theosophists. Objections to this
type of theory are numerous, and are made on
both logical and empirical grounds. First, what
could the double be made of? The possibilities
seem to range between a complete solid duplicate
and a kind of misty and insubstantial version.
Another problem with this kind of double is its
appearance. If all have a second body why does
it appear to some as a blob or globe, to other
as a flare, or light, and to yet others as a
duplicate of the physical body? Muldoon and Carrington
[MC29] wrestled with this problem and so has
Tart [Tar74b].
If
the notion of a physical double is problematic,
the notion that it travels in the physical world
is just as much so. First there are the types
of errors made in OB perception. These tend not
to be the sort of errors which might arise from
a poor perceptual system, but seem often to be
fabricated error, or additions, as well as omissions.
Then sometimes the OB world is responsive to
thought, just as in a dream the scenery can change
if the person imagines it changing; and lastly,
there is the fact that many OBEs merge into other
kinds of experience. The OBEer may find himself
seeing places such as never were on earth, or
he may meet strange monsters, religious figures
or caricature animals. All these features of
the OBE make it harder to see the OB world as
the physical world at all, and lead one to the
conclusion that the OB world is more like a world
of thoughts.
Physical Astral World Theory
(a non-physical double travels in the physical world)"
Many theories have suggested that the double is not physical but non- physical,
even though it travels in the physical world. Many occultists believe there
to be a whole range of non-physical worlds of differing qualities. Let us
look at some examples of this sort of theory to try to find out what is meant
by it.
Tart
[Tar74b, 78] refers to it as the 'natural' explanation.
He describes this theory of the OBE as follows
'... in effect there is no need to explain it;
it is just what it seems to be. Man has a non-physical
soul of some sort that is capable, under certain
conditions, of leaving the physical seat of consciousness.
While
it is like an ordinary physical body in some
ways, it is not subject to most of the physical
laws of space and time and so is able to travel
at will.' The 'theta aspect' has been mentioned
in connection with detection experiments. Morris
et. al. [MHJHR78] explain that '... the OBE may
be more than a special psi-conductive state;
they hold that it may in fact be evidence of
an aspect of the self which is capable of surviving
bodily death. For convenience, such a hypothetical
aspect of the self will hereafter be referred
to as a Theta Aspect (T.A.).'
According
to Osis and Mitchell [OM77] it is possible that
'... some part of the personality is temporarily
out of the body,' and many occult theories involve
a non- physical astral double rather than a physical
one. Blackmore criticizes this view [Bla82].
She claims if the 'soul' is to interact with
the objects of the physical world so as to perceive
them then it should not only be detectable, but
all the other problems of previous theories arise.
On the other hand, if this 'soul' does not interact
with the physical, then it cannot possibly do
what is expected of it in this theory, namely
travel in the physical world. She sees no escape
from the dilemma. Moreover, she claims there
is already evidence that what is seen in an OBE
is not, in any case, the physical world.
Mental Astral World Theory
(a non-physical double travels in a non-physical, but 'objective,' astral
world) Each of the theories presented thus far support a conclusion that
OBEs do not take place in the physical world at all, but in a thought-created
or mental world. Each of the next three types of theory start from this premise,
but they are very different and lead to totally different conceptions of
the experience.
The
term 'mental world' could mean several different
things. It could mean the purely private world
created by each of us in our thinking. One possibility
is that there is another world (or worlds) which
is mental but is in some sense shared, or objective
and in which we can all travel if we attain certain
states of consciousness. The important question
now becomes whether the OB world is peculiar
to each individual, or shared and accessible
to all.
Occultists
have suggested that there is a shared thought
world. There are many other versions of this
kind of theory. The pertinent features of this
idea are that there is a non-physical OB world
which is accessible by thought, that it is manipulable
by thought, and that it is the product of the
mind of more than just one person. Tart [74b,
78], as one of his five theories of the OBE,
suggests what he calls the 'mentally-manipulatable-state
explanation.' He raises here the familiar problem
of, as he puts it 'where the pajamas come from.'
That is, if the OBE involves the separation of
a 'spirit' or 'soul' we have to include the possibility
of spiritual dinner jackets and tie pins. Of
course any theory which postulates 'thought created'
world solves this problem.
Tart
therefore suggested that a non-physical second
body travels in a non-physical world which is
capable of being manipulated or changed by 'the
conscious and non-conscious thoughts and desires
of the person whose second body is in that space.'
In
1951 Muldoon and Carrington had come to a similar
conclusion [MC51]. Muldoon states '... one thing
is clear to me -- the clothing of the phantom
is created, and is not a counterpart of the physical
clothing.' Through his observations he came to
the conclusion that 'Thought creates in the astral,
... In fact the whole astral world is governed
by thought.' But he did not mean it was a private
world of thoughts. Also relevant here is the
occult notion of thought forms.
Theosophists
Besant and Leadbeater describe the creation of
thought forms by the mental and desire bodies,
and their manifestations as floating forms in
the mental and astral planes. All physical objects
are supposed to have their astral counterparts
and so when traveling in the astral one sees
a mixture of the astral forms of physical things
and thought created, or purely astral, entities.
There are other versions of a similar idea. For
example Whiteman questions the 'one-space theory'
of OBEs [Whi75], and Poynton follow him suggesting
'... what is described is not the physical world
as actualized by the senses of the physical body,
but a copy, more or less exact, of the physical
world' [Poy75]. Rogo [Rog78b] suggests that the
OBE takes place in a non-physical duplicate world
which is just as 'real' to the OBEer as our world
is to us.
The
idea of shared thought world, attractive as it
is, has some serious problems. The first problem
relates to how the thoughts of different people
could be combined together to create an astral
world and the second problem concerns the storage
of ideas. The idea that thoughts can persist
independently of the brain has been a cornerstone
of many occult theories, but also parapsychologists
have used a similar idea to try to explain ESP.
According
to Blackmore [Bla82] the problem is essentially
one of coding. We know that when a person remembers
something he has first processed the incoming
information, thought about it, structured it,
and turned it into a manageable form using some
sort of code. We presume that the information
persists in this form until needed when the person
can use the same coding system to retrieve it
and use it. Even if we don't understand the details
of how this system works, there is in principle
no problem for one person because he uses the
same system both in storing the material and
retrieving it.
But
if thoughts are stored in the astral world, then
we have to say that one person can store them
there and another can get them out again. And
that other person may have entirely different
ways of coding information. So how can these
thoughts in the astral possibly make sense to
him?
Nothing Leaves the Body
Parapsychological Theory
(imagination plus ESP)
The OBE might involve only imaginary traveling in a private imaginary world.
According to this type of theory, nothing leaves the body in an OBE. The
advantage of such a theory is that it avoids all the problems of the previous
ones since it involves no astral worlds and other bodies.
Certain
parapsychologists have tried to incorporate the
evidence that ESP occurs during OBEs by suggesting
that the OBE is 'imagination plus ESP' or PK.
For example, one of Tarts's five theories is
the 'hallucination-plus- psi explanation.' According
to this theory, 'For those cases of OBEs in which
veridical information about distant events is
obtained, it is postulated that ESP, which is
well proved, works on a nonconscious level, and
this information is used by the subconscious
mind to arrange the hallucinatory or dream scene
so that it corresponds to the reality scene'
[Tar78].
Osis
[Osi75] contrasts his 'ecsomatic hypothesis'
with 'traveling fantasy plus ESP' and Morris
[MHJHR78] compares the theory that 'some tangible
aspect of self can expand beyond the body' with
what he call the 'psi- favorable state' theory.
In
parapsychology many states have been thought
to be conducive to ESP. They include relaxation,
the use of ganzfeld or unpatterned stimulation,
and dreaming. There are many reasons why an OBE
might be thought of as a psi-conductive state.
Palmer suggested that it might induce attitudes
and expectations consistent with psi, thereby
facilitating its occurrence [Pal74].
This
sort of theory is not satisfying. It appears
to avoid all the previous problems and yet to
be able to cope with the paranormal aspects of
the experience. According to Blackmore 'Calling
the OBE imagination or hallucination tells us
very little, and adding the words 'plus ESP'
adds nothing. We know little enough about ESP.
It is defined negatively, and we cannot stop
and start it or control it in any way.'
Psychological Theories
This theory amounts to the statement that all the details of the OBE are
to be accounted for in psychological terms. Nothing leaves the body in an
OBE, the astral body and astral world are products of the imagination and
the OBE itself provides no hope for survival. Osis has called the followers
of such theories 'nothing but-ers,' reducing the OBE to 'nothing but a psychopathological
oddity' [Osi81].
Among
psychological approaches there have been psychoanalytic
interpretations, analogies between the 'tunnel'
and the birth experience; the creation of the
double has been seen as an act of narcissism
or as a way of denying the inevitable mortality
of the human body.
Then
there have been theories which treat the near-death
experience as a form of depersonalization or
regression to primitive modes of thinking, and
those which treat it as involving an archetype.
John Palmer used a mixture of psychological and
psychoanalytical concepts in his account [Pal78a].
He made the crucial point that the OBE is neither
potentially nor actually a psychic phenomenon.
An OBE may be associated with psychic events
but the experience itself, just like any other
experience, is not the kind of thing which can
be either psychic or not.
He
went on to suggest that the OBE almost always
occurs in a hypnagogic state. Within this state
it is triggered by a change in the person's body
concept which results from a reduction or other
change in proprioceptive stimulation. This change
then threatens the self concept and the threat
activates deep unconscious processes. These processes
try to re-establish the person's sense of individual
identity as quickly and economically as possible
in a way that follows the laws of the Freudian
primary process. According to Palmer it is this
attempt to regain identity which constitutes
the OBE. Since the whole purpose of the OBE is
to avoid a threat, the person will usually remain
unaware of that threat and of the change in body
image which precipitated it. However, Palmer
adds that it is possible, with practice, to gain
ego-control over the primary process activity.
Of course the OBE is, at best, only a partial
solution to the threat and both ego and primary
process strive to regain the normal body concept.
As soon as they succeed the OBE ends.
For
Palmer any psychic abilities which manifest themselves
during an OBE do so more because of the hypnagogic
state than because anything leaves the body.
This theory has much in its favor. It has no
need of astral bodies or other worlds and so
avoids all the problems of the earlier theories.
It makes sense of the situations in which the
OBE occurs, and the way it varies with the situation,
and it relates the OBE to other experiences.
However,
the theory is not without its own problems. It
depends heavily on the idea that the OBE is a
means of avoiding a threat to the integrity of
the individual and the anxiety which such a threat
would arouse. But it is not clear that the OBE
would not provide an even greater threat than
the original change in body concepts. Sometimes
OBEers are terrified that they will not be able
to 'get back in' which is surely also a threat.
Susan
Blackmore [Bla82] bases her theory on the claim
that the evidence of paranormal events during
the OBE is limited and unconvincing. She therefore
asserts that the claims for ESP and PK in OBEs
are not impossible but there is actually not
very much evidence which has to be 'explained
away' in this fashion. Blackmore suggests that
the OBE is best seen as an altered state of consciousness
(ASC) and is best understood in relation to other
ASCs. Everything perceived in an OBE is a product
of memory and imagination, and during the OBE
one's own imagination is more vividly experienced
than it is in everyday life. In other words the
experience is a kind of privileged peek into
the contents of one's own mind.
Blackmore
suggests that in the case of the OBE the following
are necessary: vivid and detailed imagery; low
reality testing so that memories and images may
seems 'real'; sensory input from the body reduced
or not attended to; awareness and logical thinking
maintained. She shows how these prerequisites
can lead to an altered state of which one form
is the semi- stable OBE and indicates related
states, such as lucid dreaming, and shows how
experience can change into others when conditions,
or ways or thinking, change.
This
theory accounts adequately for cases of so-called
traveling clairvoyance, where the subject does
not necessarily see his body, but is aware of
a distant scene. It accounts less well for cases
of conscious projection, where the subjects feels
himself to be at a distant location and is actually
perceived by a person at that location. It also
underestimates the veridical aspect of perception
in cases where there is no apparent distortion
by the imagination, in other words when the scene
viewed from another point of space corresponds
exactly with what one might expect to observe
from that point; for instance a room seen from
the vantage point of the ceiling. The question
of perceptual distortion is related to the degree
of interference by the imagination: the greater
the imaginative element, the less veridical the
perception of the place.
Stephen
LaBerge describes a theory in which OBEs occur
when people lose input from their sense organs,
as happens at the onset of sleep, while retaining
consciousness [LL91]. This combination of events
is especially likely when a person passes directly
from waking into REM sleep. In both states the
mind is alert and active, but in waking it is
processing sensory input from the outside world,
while in dreaming it is creating a mental model
independent of sensory input. This model includes
a body. When dreaming, we generally experience
ourselves in a body much like the 'real' one,
because that is what we are used to. However,
our internal senses reside in the physical body,
which when we are awake inform us about our position
in space and about the movement of our limbs.
This information is cut off in REM sleep. Therefore,
we can dream of doing all kinds of things with
our dream bodies -- flying, dancing, running
from monsters, being dismembered -- all while
our physical bodies lie safely in bed. During
a WILD, or sleep paralysis, the awake and alert
mind keeps up its good work of showing us the
world it expects is out there -- although it
can no longer sense it. So, then we are in a
mental dream world. Possibly we feel the cessation
of the sensation of gravity as that part of sensory
input shuts down, and then feel that we are suddenly
lighter and float up, rising from the place where
we know our real body to be lying still.
The
room around us looks about the same as it would
if we were awake, because such in image represents
our brain's best guess about where we are. If
we did not know that we had just fallen asleep,
we might well think that we were awake, still
in touch with the physical world, and that something
mighty strange was happening -- a departure of
the mind from the physical body. The unusual
feeling of leaving the body is exciting and alarming.
This, combined with the realistic imagery of
the bedroom is enough to account for the conviction
of many OBE experients' that 'it was too real
to be a dream.' Dreams, too, can be astonishingly
real, especially if you are attending to their
realness. Usually, we pass through our dreams
without thinking much about them, and upon awakening
remember little of them. Hence, they seem 'unreal.'
But waking life is also like that -- our memory
for a typical, mundane day is flat and lacking
in detail. It is only the novel, exciting, or
frightening events that leave vivid impressions.
If we stop what we are doing, we can look around
and say, 'Yes, this world looks solid and real.'
But, if you look back and try to recall, for
instance, brushing your teeth this morning, your
memory is likely to be vague and not very life-like.
Contrast this kind of event to a past event that
excited or alarmed you, which is likely to seem
much more 'real' in retrospect.
Other approaches
Perhaps all the distinctions and problems are artificial, perhaps the mind
is neither 'in' nor 'out' of the body. Grosso argues the possibility [Gro81]
that one is always 'out' and in an OBE just becomes conscious of that fact.
Should the distinction between normal and paranormal then be dropped? Let
us consider the state of affair that is considered normal: the 'in-the- body'
experience. What does it mean to be in a body? LaBerge [LL91] argues that
saying that one is in a body implies that the self is an object with definite
borders capable of being contained by the boundaries of another object --
the physical body.
However,
we do not have any evidence that the self is
such a concrete thing. What we think of as 'out-of-body'
in an OBE is the experience of the self. This
experience of being 'in' a body is normally based
on perceptual input from the senses of both the
world external to the body and the processes
within the body. These things give us a sense
of localization of the self in space. However,
it is the body, and its sense organs, that occupy
a specific locus, not the self. The self is not
the body or the brain. If we think that the self
is a product of brain function, even this does
not make it reasonable to state that the self
is in the brain -- is the meaning contained in
these words in this page?
It
may not make any sense on an objective level
to say that the self is anywhere. Rather, the
self is where it feels itself to be. Its location
is purely subjective and derived from input from
the sensory organs. Putting aside the question
of the essential nature of the self, perception
is undeniably a phenomenon tied to brain function.
So, when we find ourselves experiencing a world
that seems much like the one we are used to perceiving
with our usual equipment -- eyes, ears, etc.,
all things linked to our brains, it would be
logical to assume that it is our usual brain
creating the experience. And, if we were to really
leave our bodies -- severing all connection with
them -- it would be illogical to assume that
we would see the world in the same way.
Therefore,
LaBerge points out, although no amount of contradictory
evidence can rule out the possibility of a real
'out of body experience,' in which an individual
exists in some form entirely independent of the
body, it is highly unlikely that such a form
would utilize perceptual systems identical to
those of the physical human form. Spiritual teachings
tell us that we have a reality beyond that of
this world.
LaBerge
concludes that the OBE may not be, as it is easily
interpreted, a literal separation of the soul
from the crude physical body, but it is an indication
of the vastness of the potential that lies wholly
within our minds. 'The worlds we create in dreams
and OBEs are as real as this one, and yet hold
infinitely more variety.
How
much more exhilarating to be "out-of-body" in
a world where the only limit is the imagination
than to be in the physical world in a powerless
body of ether! Freed of the constraints imposed
by physical life, expanded by awareness that
limits can be transcended, who knows what we
could be, or become?' [LL91].
