Once, I dreamed that there was this guy calling me names, and I was annoyed, so I kicked him as hard as I could. However, I was also well aware that I was in bed, and that if I kicked, I would be kicking the wall. Still, the dream had enough hold on me that, despite me thinking, 'don't f**kING KICK THE WALL!' I full-on booted the wall. f**k me, that hurt.
