There are many working theories of what might be happening when people experience a past life. The theories include the anti-past life theory: cryptoamnesia, the concept that the subconscious has recorded historical information though books read, conversations overheard, lectures attended, and any other present life exposure to facts. These facts emerge in hypnosis as historically accurate stories and characters in specific time periods. The person having the hypnotic experience misinterprets the facts that emerge out of the unconscious as being her own past lives. Past life skeptics love this theory to explain away past lives. Then, there is the theory that our imagination creates the past lives the same way that our imagination creates our dreams.
