I actually agree with you there. I have NEVER flown in NDs before, but the first thing I did when I got my first lucid dream that didn’t die after a couple of seconds, was fly over my house and just float there on top of the roof. The first time I used what I call the “rocket method” - jumping, and then flying straight upwards, before gliding forwards once I’d reached the roof, and arcing down to the ground on the other side. The second time I flew on my belly with arms tucked in, although I started to feel my bed underneath me when I was losing lucidity there. Both times it has felt so natural, and has been the first thing to come to mind when I become lucid. Mind you, I haven’t flown since then, because I’ve been making a conscious effort to try other things instead!
