One night, when I was just sleeping. I was seeing a pencil dangling by a tree branch and the point was facing my neck (I think I might have been facing upwards, I'm not sure) and I imagined the pencil falling for some reason (this wasn't a dream). Once it "hit my neck" in reality my neck started feeling really really weird, like someone did something to it. That was the first time the my thoughts before I fell asleep affected me (or anything in my mind affected me) in real life...
