Once. I dreamt that I was wandering through a field of people who all looked identical to me (a detail which, in the dream, didn't seem at all strange.) One of these "Hector"s, dressed in a suit, came up to me and asked me to play paper scissors rock. I said "yes", we played, and he beat me with rock. He announced that I lost, and then held a gun to my chest. Suddenly, I was cut to a scene where I was asleep on the couch, and the suited Hector held a gun to sleeping Hector's back and fired.
Yeah, my dreams are pretty wtf. :<
