The night before last I dreampt that I was being held prisoner by a serial killer, who had an old house and wielded a machete. The first floor of the house (2nd floor for US readers) had a huge hole in it. The killer was making his prisoners jump barefoot from the first to the ground floor, onto the rough concrete below. Soon the guy became impatient with us and began to attack us with the machete. As he bludgeoned some of us I could hear a banging sound (which I took to be the impacts of the blade). Soon I woke up, but the banging carried on.
It turned out my next door neighbours were having a new kitchen fitted.
