This is a very interesting topic that I think I could write a book on if I were to associate my own experiences to my ideas and perceptions of the different theories involved.

You did a good job explaining the ideas of parallel versions of reality.

I wonder if the conscious mind would be copies of the same mind or somehow all connected in an unperceivable way to the main body of conscious mind.

I've wondered if conscious mind is a simulation, and if is somehow identical copies how many could or would there be? Is it an expanding process, where conscious mind shifts around and might explain phenomenon like the Mandela effect?

I wonder if one has a near death experience that was miraculously survived the conscious mind just unconsciously shifted conscious mind to another reality where the one in a million chance of survival occurred.
