I think about this a lot. In my dreams, flying feels as natural as walking. Even crazy superpowers I invent and try for the first time work exactly as I expect because it's a dream and everything works as I expect. For a while, I even believed my lucid dream self was my true form and my waking body was just a less-than-authentic character I control in the real world. I now understand that dreams only feel more real than reality because dreams are 100% intuitive. Still, I can't help that being flightless still feels like a disability sometimes. I find myself craving the feeling of flying while I'm awake and unable to experience it.

I don't think I've had full flight in my dreams. I have had a recurring one with near flight. Maybe you can try it.
I am in a suburb. One to idealic to be real, perfect weather, and very quite. Im outside on a lawn. I discover I can climb stairs that are not there. I just sort of walk up into the sky as though there are steps under my feet.
Eventually I jump from a very high point. no fear I feel like I've done this before. When I land I find I can jump back up to the height I have fallen. So I just jump from roof to roof. If feels very nice though telephone wires concern me a bit.
