Where do you get the idea that we're all connected? Do you believe that rather than being born in different timelines, our different "selves" only split off over time?

[They're really in it, now - in a pointless hypothetical philosophy exercise.]

Don't you think that if that were the case, and our overarching soul, or whatever you want to call it, weren't whole and reunited until all our selves died, we'd feel it diminish over the course of our life as new selves split off?
