See reincarnation .
"Metempsychosis is another term for reincarnation. Not too many people are familiar with this word."

not just "reincarnation," but the experience of the transmigration of the soul. and contrary to the other definition posted here, quite a few people know the meaning of this word.
all examples are even more speculative than the definition, so i will resist.
