The Erratic dreams of StaySharp

Another world:
I was in a totally different world from here and remember going through a lot of places, everything was a lot more advanced then here, with me starting in some sort of huge highway and then going through a city of sorts. I was with some people and the biggest thing I remember was an conversation with someone what was being controlled by a psychopath. We managed to capture and restrict him and while I was about 3 meter away from him I said I was absolutely going to kill him if I saw him one more time like that. After no significant response I came closer and asked in a threatening way if he would rather lose his life now. At that point I saw he had a flashing headband which was the thing that partially controlled him. He answered with an obvious "no". I repeated myself and said something like: "Do you want to die being controlled by a psychopath or do you want to try living?", on which he again responded he wanted to live so we helped him get rid of that headband.

TF2, way of the scout:
In a dream I was thinking about which team a scout would go with an BLU mother and an RED father, and a short story emerged. The scout went to the RED team first following his father but since he didn't really like his father and BLU always lost he decided to join BLU to prove that RED won't always win the payload races.

Some Harry Potter stuff:
Harry and some other people were in a huge building, chased by something strange flying which they couldn't hit at all. Se he decided to mix a potion which would create a weapon which couldn't be heared (or probably sensed otherwise) and got some admiration for his mixing skills.
