Yes! All possible realities exist and we just experience the ones that on some level we chose to. If you laid each snapshot out next to each other, we experience time as moving down a straight line through one current in order to create a story like a movie. When we dream we kind of float around and experience realities without as much restriction although usually within our vicinity (so that we experience as the same identity that we do in waking life). I imagine when we die it would resemble that and that we could choose to live any one of infinite versions of whatever life we choose.

I hope to see more on steemit who want to talk about these topics.
