The quantum wavefunction is what's real. Your collapsed "reality" is an illusion, an effect. One among probably literally infinite variations of collapsed "realities," all coexisting within the wavefunction. With each passing moment of time, alternate realities are splintering off from yours. Infinite "you"s, branching off in slightly different directions, going off on their own way, never to be seen again. You'll end up going down only one of those infinite paths. But ... which one? Which "you" will you be?
