When I was seven years old, I had a nightmare that my babysitter was babysitting me on Halloween, and suddenly my brother and babysitter became possessed (and naked, which I guess my mind thought was a side effect of being possessed) and started trying to catch me to kill me. In the end they tied me to the ceiling fan and turned the ceiling fan on. That's when I woke up. It's not that scary of a dream looking back, but it was pretty scary when I was so young.
