One of my favorite lucid dreams was when I was being chased by some monster. Somehow I realized it was just a dream and I wanted to try a neat way to get away. So I stuck out my index finger and drew a big circle in air. This circle became a portal through whcih I jumped and was in a different dream. It was different only because the environment seamed to have change from dark and chaotic to calm and open. When I jumped I also changed form into something like a gargoyle. The monster chased into this dream as well, but I either got away or woke up cause that's as much as I remember.
