I have been trying to get into controling my dreams lately, but come out with nothing. When I become lucid, I can barely fly sometimes. There was one rare case when I became lucid and was in a busy part of a big city (like New York maybe) and I all of a sudden became mad. For that reason (the library wasn't open, which happens alot to me in real life), I became lucid and bagan picking up cars and trucks of all sorts and hurling them through massive buildings. I would hop, come down, and smash cars and people to little pieces.

This was the most funnist lucid dream I've had. How can I gain better lucid control in my dreams?
