I dreamt last night that I was a serial killer who offed young men by injecting them with something that made them poop to death. My favorite way was to do this right before they were about to get in a public swimming pool, so everyone around them got poo-covered. I was totally remorseless, too, and was only worried about making sure no one suspected me so I could go on doing my thing.
I was really disturbed when I woke up from that.
