Yeah i know what you mean. In my lucid dreams, there is usually always a point where I am truly lucid. Whenever I'm flying (or trying... to fly) it's usually no where near as cool as when I first become lucid. I realize that since I can't fly very much (and it isn't that exciting and i lose lucidity easier) I should just walk around and explore and stuff. I love it when I'm absoulutely lucid for a couple of seconds and I feel as if it were as clear as reality. If every moment of my lucid dreams were like this it would be insane (but the problem is once I realize how lucid i am I try to start flying and my confidence level is very low at flying because of how many times I failed).
