Could be worse, I suppose. 

A friend of mine once got so sleep-deprived that we were talking and all of a sudden she froze, staring wide-eyed at something behind me. She claimed I was being stalked by Slenderman. 

Later that night, we were talking online and she told me her Christmas tree just exploded into a swarm of butterflies.

...So yeah moral of the story is, just make sure you're sleeping in the first place, I suppose.
