I'm kind of interested in this subject at the moment. I've heard about these records years ago when looking up information on Rudolf Steiner.

Around 2002 or 3 I had gone to one of Dr. Grof 's Holotropic Breathwork 2 day event at Palo Alto, I think I reverted back to a fetus but not really all that certain. My breathing partner reverted back to the time he was a being born(he was a forceps baby), he said he was in a dark cave and someone was after him with daggers, talk about early trauma. I seen some pretty weird stuff at that event.
The Mystics have long said that every thing is just one thing Consciousness, which I think many scientist can agree. To me it is kind of like a superior intelligence is all by himself and to fight loneliness decides to make all these different types things that give him an experience, seem plausible.
