From personal experience what works for me is not try to master anything but rather give the dream world a life of it's own. Not sure if that makes sense but when I attain lucidity I see that world as it's own living organism. Is it really? I don't think anyone knows for sure but from what I have gathered I seemed to do a lot better if I master my techniques, and yes my body process and not so much what's on the other side. Hope this helps.
