Spoiler? Theory?
my friend at one point was talking about this infinite life theory ( something like that) where when you die you get warped to a different you from a another universe that was parallel to your original one.
after the park ben has a scar on his back that wasn't there before that would be a fatly wound, so what if when he died in one universe he hoped to a new one and his dreams are true life but from the universe he left
I hope I explained myself ok
