PhilSmiths - People say such things without ever having actually explored - not interpreted - a dream of flying. Flying is an act of confidence unless using it to escape from difficulties. Flying as if swimming shows that you are still learning. It is something people do as they learn how to cope with their inner world. See
http://dreamhawk.com/inner-life/inner-world/What does it matter what various religions say of flying. Most of them were written in periods where people had very different mind sets or worldview. For instance Christianity was written for a largely farming community, and so much of the language made sense to them, but it largely not understood today. Also much of it was stuck in symbolic statement.
But you can find out for yourself if you learn how. See

http://dreamhawk.com/dream-encyclopedia/questions-2/#Summing ‘During childhood I learned to fly in a long sequence of dreams. Each linked very clearly to the last. I would go to the nearby churchyard and in the beginning I would run along as fast as I could then jump and just manage to extend the jump by a great effort of will. In subsequent practices I managed to gradually extend the jump for many yards; and eventually I could skim along indefinitely. The next stage though was to extend my height, and this took enormous effort of will and body. I made active swimming motions and climbed, but only held altitude with great and constant concentration. With further practice still, this clumsy mode of flying was left behind as I learned to use pure motivation or will to lift me into the air and carry me easily and gracefully wherever I wished. At this stage my flying was swift, mobile and without struggle'.
