That's freaky and kind of cool the way your dream was glitching out. Did you actually get to a point where you were still asleep but there was nothing there? I've never been able to do that without waking up.
After writing my article, I had a few people tell me that they were able to control their dreams, no problem. One guy said that he created a whole world that he returns to every night, with a dream wife and family. So I guess it's possible and maybe worth working towards, but I still do better when I work with my subconscious instead of ordering it around.
