When I was a little girl, I wanted more than anything to be able to fly like a bird. My experiments with "flying" down the stairs (from the 2nd to the first floor of our house) were not successful even when I used a bath towel as a cape (a la Superman), and they were not at all popular with my mom. The only time I could fly was in my sleep. I would have marvelous dreams about flying and wished I could dream those dreams on command. At intervals throughout my adult life, I've had other dreams about flying - in some of them, I couldn't NOT fly - could not keep my feet on the ground (that probably says something about my personality, but I don't have the time to analyze it right now).
I think Patch has dreams about flying sometime.
