I fell asleep in yoga class.

They tell you to lay on your back, so you do. Then the lady has you close your eyes and starts describing how comfortable and relaxed you feel, and you're like, well, come to think of it, I am feeling particularly peaceful. So you follow directions... and the next thing you know, you open your eyes and everyone is standing up. Except for you. Still lying there on your back. Like a doof.
