My 4th lucid came about when I realized I was attempting to fly. I remembered to look up to go up, and down for down. I had very little propulsion but going up and down was neat. This was my first time consciously being able to fly. I think it's a great way to start lucid dreaming as it strenghtens your control. In my past lucids, I tried conjuring very complicated and elaborate scenarios, that were too much for a newbie.
