There's a really interesting book you might want to check out called 'Life Between Life' by Dr. Joel L. Whitton M.D. Ph.D. first published by Warner Books in 1986 ISBN 0-446-34762-0
The ancient Tibetans called it 'bardo'. Dr. Joel L. Whitton, metaphysical expert and researcher, calls it metaconsciousness. It's the wondrous state that occurs after death -- the threshold of consciousness that separates one incarnation from another.
Based upon thirteen years of research and more than thirty medical case histories, and drawing on the revolutionary technique of hynotic regression, Dr. Whitton and Joe Fisher, himself an expert on reincarnation, take you back into the past lives of contemporary men and women.
They lay out the amazing stories of their subjects -- who they were, how their past problems reach into their present, and what it's like in that extraordinary time between lives.
