There is information online that will tell you how to have a lucid dream. I got into it for a short while back before the internet. I have had a handful of them. The problem for me was that once I realized I was in a dream I would start to slowly wake up, so I would have to distract myself to keep the lucid dream going. Once I became lucid in the dream, people would stop talking and basically just stand where they were. I flew one time -- I climbed out a window on something like the fifth floor of a building. I was scared to death because I kept wondering "what if I am not dreaming". It was not like Superman flying, more like the guy from "The Greatest American Hero", if you are familiar with the show.
