Time Paradox: If you were to go back in time and see your memory get erased, you couldn't remember your memory being erased because your memory was erased and your future self wouldn't remember that because your past self had already gotten his memory erased, but at the same time you could remember because you are seeing yourself getting your memory erased, so you could remember that because your future self could still remember that event by seeing it. Your mind just got blown, amirite?
