The moment when you see someone on the street, and you just can't recall where on earth you have seen this guy before.
Hmmm, what if, you and him met in another parallel universe and you happened to travel to that universe by accident and your consciousness sealed all this into your deepest part of your mind and for that second some leaked out and you thought you knew this guy in the current universe you are on?
Time travel, jumper, looper, parallel universes, how fascinating they are.
Yeah...
