Probably the creepiest thing I felt actually amused by. One of my most formative experiences was a childhood nightmare where I actually felt myself slowly waking up after being confronted with a monstrous image. I don't know if it was sleep paralysis, but I always think about that most terrifying experience of mine when the topic comes up. Just looking through the different options made me tense about continuing, and yet I felt I had to see all the combinations.
