I'd look up and memorize winning lottery numbers, then teleport back two weeks ago. (4-d space!) And then I'd just buy a lotto ticket and chill until my past self becomes my current self, but with lottery money.
Teleportation only works in spacial dimensions. You have now teleported to a slice of the 4th dimension that only houses the very edge of your known reality, making everything distorted from your point of view, and everyone will see you as a monster as you no longer resemble a human, but a blob.
