I had a non-lucid dream I thought would be worth sharing, so here it goes:

I'm in a dark room with another person. He was shaking of fear, holding a large knife and he was very afraid of me. I felt mighty and invincible myself. He approached me with the knife, and I stood still. He started cutting me with it, but I did nothing and I ignored the knife cutting through my flesh. After a while, he ceased cutting me and dropped the knife. Now I lifted him up, ripped his head off and threw it away.
