I think that is certainly possible, after this receiver of consciousness stops living, we very well could go on to a higher level dimension where, I suppose we could relive moments or as you say, watch them and how they unfold based on different decisions parallel "us" makes. I've been thinking more and more, that "God" or the creator of the universe, or Einsteins "whatever set the laws of physics into motion", has most likely created some sort of test spaces - infinite universes with infinite possibilities, to maybe understand where "It" came from?
