I had a dream where I was walking up to a bridge the size of the Brooklyn bridge or Bay bridge on the way somewhere. Once I was on the bridge I jumped up and flew hundreds of feet into the air completely under my own control and volition, then slowly fell back down, and then jumped off again. I did this several times - it felt like jumping up and down normally but with a tiny fraction of Earth's gravity present.
Later in the same dream, I did something similar, though this time it was on a wide, cobblestone city street on a rainy night and rather than jump up and down I simply took off and flew.
