I've flown and done the obvious(you know) in lucid dreams. Those were lucid dreams that I could enjoy. Normally when I become aware of the fact that I am dreaming, it's when I'm having a nightmare(death, murder, etc). I'm so relieved that I am only dreaming the nightmare, I "steer" the dream another direction and fall back into a less aware sleep, forgetting the rest of the dream.
Now on a very rare occasion I do get a lucid dream that doesn't involve being scared to death. Those are really, really fun. The feeling of flying was amazing, and this is coming from someone who is scared of heights. My lucid dream allowed me to bypass my fear of heights, and soar through the skies like a bird. Sweet:)
