I dreamt that I was in a public toilet, and an old guy was just standing in front of a urinal, and all of the other ones were taken. He walked off and I took his place and was just about to go when he budged me out of the way and emptied a kettle of water into the urinal. He walked off and I started to go, and then I noticed there was vomit on the urinal, and he had been flushing it with the kettle. I remember thinking that it was nice of him to clean up after himself, but where did he get the kettle from?
