Well, one day I went to my grandpa's for a sleepover. I slept in his bedroom, and right before I went to bed, I suddenly got extremely thirsty. There was a random glass of water, right next to the bed on the dresser, so I drank out of it, and refilled it, thinking nothing about it.

The next night, I saw that same glass of water, but with my grandpas false teeth floating in it.
