Usually when I'm very sure that I'm flying (not hover/camera angle-ing lol) I have wings. First time I remember the wings they were white and big like angel wings. For me I don't think it's the feeling of weightlessness that allows me to fly, but the freedom that I feel within the dream. I'm no expert on flying in dreams, but you could always just try feeling free, though that may sound silly. Though now that I think about it...I hardly every feel gravity as it is in reality. Most of the time it just feels like everything is off kilter. Kinda like I'm leaning to the side (tin man in wizard of oz anyone?).
