Floating and flying: Dream meaning of effortless Freedom

"I was walking down a street when I suddenly lifted off the ground. There was nothing on my back and I wasn't using anything. I just kind of floated up. I remember looking down at my shoes and thinking, how am I doing this? I tried moving my arms and it actually made me go higher. It felt almost like swimming, except there was nothing around me. I went over some houses and then over a road. I wasn't thinking about where I was going. Then I was suddenly inside a grocery store, still floating. People were shopping like nothing was strange. I wanted to show someone, but when I tried to talk, nobody looked at me. A moment later I was outside again, much higher than before. The wind pushed me sideways and I started laughing because I couldn't control where I was going. Then I dropped back down and landed on a sidewalk. I looked at my hands, tried to fly again, and couldn't. I woke up wishing I could do it one more time."
