I dream of this since I was a child. Since I was 7 or so.
We used to live in a big open house. In my first dream I took off from the big patio, learning to float/fly/travel in air naturally, like learning to walk. What induced this flight was a state of concentration, and an explicit desire to fly (like you 'will' to raise your hand and are able to do it). The problem was I couldnt enjoy the view outside as I had to keep observing the sensations inside to maintain the concentration. Better the concentration, better was my control over steering and even maintaining the flight. I learnt to do this.
I had to learn to identify what held the concentration, what kept my mind aware, agile and light, to keep me attuned to flight and give better control over the flight. As an amateur, initially it seemed to happen on its own, and flight was awkward. Then the mechanism ... I discover there is a mechanism. After some years I begin to feel more confident and take off like a confident hang glider getting good currents, but sometimes I would be too off-tuned to concentrate, the mind had to be clear and concentrated for a good flight and it seemed to have some pre-conditions to concentrate (not aware precisely what though).
I had to learn able to identify and hold on to the right state of concentration: it was not a deep or sleeping sort of concentration, rather something agile and active, clear and pure at the same time - yet concentrated! It was usually difficult to keep the mind pure and not too excited, or too dull!
I later saw the recurrent dream was always from the current place of residence, wherever my house was at that point of time. The ability to concentrate and relating that to flight was the common theme. The interesting thing was these seemed like very true experiences, now when I remember them, and for the first time identify it as recurrent dream-state, for the first time I remember a recurrent dream over twenty years in a full state of wakefulness!
