Dreams.

I recently had a dream about a game similar to Diablo, but even better. I was playing as some hunched and skinny guy, resembling a zombie, and I was fighting almost identical monsters. My weapon was a metallic disc (hello, Mafia!), which I threw at the zombies. It made a circle and returned to me, hitting the zombies again. It also hit other zombies because it flew like a boomerang, i.e., in a semicircle. That's it. And before that, I think I was playing as someone else, I don't remember.

And today, I had another dream about some kind of catastrophe. Maybe it was the end of the world, and I had to escape.
