Right now we live in three dimensions, right?
Maybe in the next life we'll live in 4 dimensions. Or maybe the world will be inside out and physics will look screwed. Or possibly everything will be a shade of gray. Maybe the Earth actually will be flat, but once you hit one end you come out the other, like in pac-man. Maybe the world will be made of pixels, like minecraft.
In short, once you die, you could "move" to a number of multiple universes with different rules of physics.
Also to the four dimensions thing, I'd LOVE to write in a 3d space.
