I have always had trouble with my lucid dreams. My dreams usually end very quickly as soon as I become lucid. My lucidity makes the dream unstable. I often can't think of something to do before the dream ends. And that is probably caused by the fact most of my lucid dreams have low lucidity levels, so not all of me is there. But a few days ago, I finally got to fly in a lucid dream. I didn't get to before because of all the causes I listed. But I did it. How was it? It was great. I gleefully jumped out of a window and flew over a valley.
