Just read a great article about learning to fly in LD's. The swimming technique you mentioned sounds great and in the article, I read that you can ask a DC to teach you to fly. I just realized that you could probably have DC's teach you to do anything. So if I wanted to learn dream control, I could find a master dream control DC to teach me. Or if I wanted to get better at a sport, find a world class trainer DC for that sport.

So I'm going to be using DC's in my dreams to teach me to do things. Hopefully, this will work out great.
