So true about this having elements of Buddhism! Your theory is pretty fascinating. I do know we've hit a sort of brick wall in our evolution where it's clear we must evolve in a direction where power doesn't corrupt us. This seems to be one of the biggest stumbling blocks of our species. Only a very few of us can attain positions of power and not use it in nefarious ways...this was the part of the dream that reminded me so much of The Lord of the Rings.

If the infinite universe theory is correct everything we dream actually happens/happened.
