This happened a few years ago.

I had stayed up all night during a sleepover at my friends house on a Friday night and went to dance the next day.

Well my sister usually had an extra hour of dance so I would sit on the couch and watch every Saturday.

So I decided to lay down and apparently I fell asleep and dreamed that I watched them dance and never fell asleep. So when I woke up, I didn't realize I had been asleep.

I got up and looked at myself in the giant mirror covering the entire wall.

The entire class had drawn on my face.
