Raziel 314 , you know that we all go out of body druing deep sleep , so you know about the astral world . Is this from personal exp. or from a book ? If its just one book read a few more , like ones by Robert Monroe , William Buhlman , Erin Pavlina or D ick Sutphen , and a number of others . When you said its a trap , I was thinking more of the line " dont go in to the white light its a trap " . Not by belief but some think that way . Make some follow up comments , dont make me put you in my post and split bin .

p.s. If any one hear does not know about a.p. /o.b.e.
