It's like when people do past life hypnosis, everyone is a King or a Warrior or an Aristocrat
(Clairvoyant) Ah yes I am seeing your past life, you were an utterly unremarkable person, doing the same things people around you did, saying the same things people around you said, neither especially kind or cruel, but making sure that you stayed alive as much as you could help it.
A PhD student once mentioned to me that when people envisage themselves in history, they always assume they'd be upper class. No one ever thinks that they'll be poor :-)
