Give the person above the Most USELESS Super Power!

Ability to move through parallel worlds. but the parallel worlds only have minor changes like X number of sand in sand box instead of X-1 number of granules.

Ability to automatically shift into parallel worlds every Sunday, but you have no memory of the previous world and only the memories of your current self at the time. You do not have control of which realities you enter, and they are only realities where an alternate you exists.
