Great post, here's something additional to consider. We are 3 dimensional creatures, simply perceiving the 4th dimension (Time), in a seemingly linear fashion, albeit moving through time at different rates based on mass and speed. Time however, would exist to 5th or higher dimensional creatures as something to be observed, from start to finish, and were there a multiverse - every decision and action taken by the infinite versions of "you", would be observable as well (in a sense everything that can possibly happen, has already happened). Perhaps our consciousness, just by running through scenarios of potential futures and ruminating on the past - we are experiencing glimpses into these parallel universes, every thought therefore would be connecting us to these infinite versions of us - kind of like your take on dreams - but expanded to include all of thought (except being mindful in the present moment I suppose). Interesting post! Cheers.
