Dreams.

I used to work as a police officer. Together with my partner, we tracked down a robber who, over n years, dug an underground tunnel from his house to the bank and stole 11 cents (lol). At the scene, it turned out that the criminal was an angry old woman, the kind that usually sits by the entrances of buildings. She pulled out a kitchen knife and slowly hobbled towards me. So, I said something like, "ha-ha, finally an attack on a police officer in the line of duty!", and then I shot her.
