What If Time Sometimes Flowed Backward But Only For You?

Imagine, you are sitting in a boring class, staring at the clock. And suddenly, it moves backward. Everything just rewinds. The people talking, the notes you just took, the notes the teacher just wrote on the board. Everyone moves in reverse. But not you. 

Nobody notices anything strange. You are the only one moving forward in a world rewinding itself like in a movie. 

You watch conversations un-happen. Arguments un-break. Smiles disappear before they’re made. And then, just as suddenly as it happens, it stops. Everything returns to normal. Everybody goes about their business as though nothing has changed. 

Would you try to warn someone? Or maybe time isn’t broken at all… but trying to show you something you missed the first time around?
