What happens when you cram for an algebra exam? You get an OOBE.

 I took a quick nap in the afternoon, and promptly had an Out Of Body Experience. At first I thought it was just a bad dream, but as I floated around what looked like my body lying on the bed, and carefully looked at the different things in the room, I wondered if I had experienced bangungot, or something.

 Several minutes and litanies later, I managed to slip back in and "wake up."

 I'm done with Math!
