I had one once, where the I was in school. A little boy with no fingers came to me, with a hand axe in his mouth. I took it and he told me to kill. I think i chopped up all kinds of people. Friends, enemies, etc. Then the little boy became a snake and began feasting on them, but it wasn't really their bodies, but their souls. After that I woke up...went back to sleep. Then the little boy came back again, he held a girl's head in his mouth (by the hair) and told me to rip her skull up. I woke up again and didn't sleep for the rest of the day.
