When I eventually succeeded in falling asleep, I had a dream. In the dream, I was killing someone. I thrust a knife into their stomach with all my strength, then reached into the wound and wrenched out the long, coiled-up intestines. Like eating fish, I peeled off all the squishy flesh and muscle and left only the bones. But in the very instant I woke up, I ceased to remember who it was that I had killed.
