- I very much enjoyed the wise words of Dr. Rampa, but I would like to add
- something to one of the statements made. It was mentioned that many people
- experience an uncomfortable jerk throughout their body as they are falling
- asleep, sometimes accompanied by a 'slam' feeling in the head. If I may
- offer a temporal factoid, this is called a 'myoclonic jerk' and has a well
- established neurophysiological explaination. As you are falling asleep, your
- midbrain changes some of the ways it allows messages in and out of the
- brain. One of these is to reduce the activity level of the cerebellum
- (coordinator of muscle movement, that straited body at the posterior base of
- your brain). As this is happening, the cerebellum sometimes experiences a
- momentary blast of neuron activity (basically a fleeting seisure) that
- causes most voluntary muscles to forcefully contract -- thus, the myoclonic
- jerk.
-
- Incidentally, when one dreams, your midbrain shuts out ALL muscular messages
- from brain to body, resulting in the oft-mentioned 'sleep paralysis'. (It is
- not a hormone). In perfectly normal people, this mechanism sometimes slips,
- thus sleepwalking/talking etc. There is a disorder in which the area
- responsible is dysfunctional, and people vigorously act out their dreams as
- if they were real, often causing bodily harm to themselves or their sleeping
- companion (if treatment is unsuccessful, they have to sleep in soft
- restraints).
-
- I have been very interested to read that the 'repercussions' felt by
- OOBE'ers are an experience very similar to myoclonic jerks. However, you
- can do an EEG and *see* it in the neurons. Does this, then, mean that it
- is a purely mundane-physical phenomena, and has nothing to do with some
- "astral body"? No one can really answer that, because modern neuroscience
- has no answer for how consciousness emerges from the physical brain. Thus,
- it could be that the experience of astral travel and the EEG-observable
- brain phenomena are part of the same phenomena -- the separation of
- consciousness from physical form. Who knows?
