Dreams.

I had a dream that we were playing a game with some friends, divided into two teams and fighting each other. But we weren't in our own bodies; if I understood correctly, we were in game avatars, meaning we were controlling different bodies. I realized this when I saw a guy next to me, the same one I had just killed and whose fingers I had cut off, trying to take his rings. I think they were pleased with my persistence and determination to win, but the brutality was a bit much. And I still remember cutting off his fingers with a knife, and it wasn't that easy; it was like I was sawing them off. As for the location, it looked like one of the towers from the game.
