I've had a similar train of thoughts for a very long time now, since my childhood in fact, it being that, as one is born with a consciousness, it is likely that when one dies, one will gain a new consciousness, a new spirit in a new body, but while being unable to remember of what happened before. To be more precise, it would result in a new existence in the physical world, with a "normal" consciousness; yet, there'd be no connection at all with the past self. I however was never able to find literature on the subject (not scientific literature of course, but rather philosophical or esoteric), probably because I'm not using the right terms when searching for it, but there must be writings about such a theory. "Reincarnation" doesn't seem to be the appropriate term as it's mostly used in religious contexts and often implies the ability for one to remember one's past self. Drawing on your comment, perhaps you may know what terms could illustrate this idea?
