radio clip of program on pilots losing conciousness due to the high force put on the body:

Sometimes an OBE type experience has been induced by extreme conditions. G-LOC can induce something that seems like an OBE. The high force causes the blood to drain from the brain, which causes loss of conciousness. While unconcious, some people imagine they are doing something familiar. But sometimes they imagine they are out of the body looking down on it. Why would they imagine they are doing something that most people would claim they have never done (while on the other hand most of us have been to the grocery store). Is the model given adequate to explain what has happened?

  To some extent, the above article reminds me of the research of that researcher that exposes volunteers and their brains to strong magnetic fields and then people describe various nonphysical type phenomena... 

To some extent it reminds me that Edgar Cayce, as a young child, fell head first onto a board with a large nail sticking out of it and it deeply pierced into his forehead...

  To some extent it reminds me of the repeated messages i've received from guidance to eat "mummy food", which in the Cayce readings was recommended as "almost a spiritual food..."

   To some extent it reminds me of Ah So's dietary advice to Rosalind McKnight and Bob Monroe in the book "Cosmic Journey" about the importance of eating natural, not eating too much, and eating less and less meat and especially avoiding the heavier, denser meats like beef and pork and sticking to the lighter meats of fish and fowl.

   I guess what i'm saying is that what we perceive as the physical body, is really "consciousness" too, and consciousness that's energetically entwined and intermingled with our so called "nonphysical" consciousness part of us which is self aware, freewilled, eternal, etc. 

  In the further future, humans will begin to fully understand the holistic nature of the interconnection between that which we call "physical" and that which we call and label "nonphysical".  We will understand better that affecting the physical can sometimes affect the perception and perceptual capacity of the physical to the nonphysical, until we completely transcend the physical "rule sets" by completely and permanently attuning to Love. 

  We will understand that truly the physical body is the Temple, and should be treated like such, and not like a pig sty like those like Edgar Cayce, Bob Monroe, and other notables treated it like. 

  We will understand that if you treat the body like a Temple, and feed it only health and life promoting foods and exercise properly, that it facilitates and strengthens the ability of the nonphysical part of you, to better and more clearly and strongly shine through the physical part or level of you into this level of consciousness, this dimension. 

   This is why, probably, that i've been directed to eat a more and more strict and health promoting diet--particularly urged to eat lots of raw and live foods (particularly large amounts of salads), easier to digest natural and nutrition packed foods, avoid junk foods, avoid heavier meats, avoid most sugars, urged to eat less, etc, etc., etc.  Or why, when i was directed to fast for 7 days, towards the end of same i had certain powerful revelations and guidance messages (like that most recent dream i shared talking about Bob's inphysical female self.).

  Perhaps this is even why Yeshua, who sometimes downplayed the role of the body in some ways, decided to fast for 40 days before going out and publicly teaching?  Perhaps he knew and felt that he needed to cleanse the vehicle to better align it to the Spirit Consciousness within, so that he could and would be able to better express that attunement within the physical?

oh this looks interesting but I haven't read it yet

I don't think going unconcious from experiencing a high G force is equivalent to regular falling asleep, though I am not sure exactly what causes one to fall asleep. But if it was from the blood leaving the brain I'm afraid we might all diewhen we went to sleep!

Also, I'm not of the belief that the only way to experience an OBE is that you must be completely asleep.  Perhaps what is considered light sleep, but we can do lots of things while in that kind of state and not even realize we're sleeping.
