Just thought I'd add a comment. I have a lot of flying dreams (Often because I dream of being Peter Pan, I don't know why. Maybe because it's the earliest movie I remember saying, "wow that would be so cool). But I actually Identify with you flying technique a) as I have done it often in my dreams! I've also had some, and this will probably sound strange, where I can hold my breath and float like a balloon and when I breath out I sink, lol.
