I enjoyed your story of transforming a scary dream with monsters into... Well... Something else. I don't think I ever managed to exert this kind of influence on any of the lucid dreams that I have had.
Every time I start lucidly dreaming, I just have to try to fly. It is too much fun, and the temptation is nearly overwhelming. It is not exactly flying, but more like hugely exaggerated jumping like in the film "Crouching Tiger Hidden Dragon."
I first began to pursue it as a youth after reading Castaneda. After some time, I put much less weight on it as a tool for concretely affecting my everday, waking life.
I still think it could be a very interesting tool for writers to explore the furthest bounds of their imagination.
