Last night I dreamed that I was in a Mortal Kombat fight, and my character was Lucifer (Peter Stormare from Constantine) with a goofy laughing expression on his face and he could shoot purple lasers out his eyes. (Edit hold on i have to generate this i don't know you didn't ask but HERE)
I've tried a few times but it makes it harder to fall asleep. The most success I've had with it was when I was really tired and fell asleep watching a badly translated version of one of the original Star Wars films (empire strikes back?).
