Could it be true... just one person?
Well what if you consider the smallest amount of time that could possibly be experienced...
Then consider that we may not all experience this time at the same time as everyone (and everything) else...
Then it would be possible for one living entity to move between all people (and things) without overlap...
Perhaps we're all the same experiential entity moving between to experience the different lives...
Maybe it's true, just that memory is stuck in the body and we could never possibly remember having been in someone else due to the non-transferable state of the memory...
Does this hypothesis have any strength? Let me know what you think...
