I have been following a discussion on a different forum which discusses the collective unconscious and the holographic universe and how they may be alternative explanations to reincarnation. The people on this other forum are believers in the afterlife and are not atheist skeptics. However, they reject reincarnation. The argument that they put forward is that the phenomenon of children remembering past lives is caused by children accessing other people's memories through a collective unconscious like the one suggested by Carl Jung. They also put forward that if the universe truly is holographic then no one set of memories would be unique to one person because each individual contains all data contained in the hologram. They also mentioned the work of Ian Stevenson and said that his work would have been proof of reincarnation had it not been for a few of his cases which seem to be more suggestive of the collective unconscious. These cases of Ian Stevenson were cases in which one boy remembered being a man who was still alive and another case in which two different boys claimed to have been the same person. Does anybody know anything about these cases or could anyone enlighten me as to how this idea of a collective unconscious in place of reincarnation is flawed as a premise?
