I just went back into my copy of Introductory Lectures on Psycho-Analysis from college to look up symbolism in dreams. I'd had one about quelques tours en l'air (a ballet jump where one leaps and turns one- to several times in the air) in which I could jump and then, Mary Poppins style, continue rotating casually much longer than gravity should have permitted. So I went to look up dreams about flying, only remembering something about their having to do with sex:
Dreams can symbolize erection in yet another, far more expressive manner. They can treat the sexual organ as the essence of the dreamer's whole person and make him himself fly. ...And do not make an objection out of the fact that women can have the same flying dreams as men. Remember, rather, that our dreams aim at being the fulfillments of wishes and that the wish to be a man is found so frequently, consciously or unconsciously, in women.
Right. That's it. My flying dreams are not, in fact, anything to do with a desire to escape the bounds of gravity (daily life) and to ascend to something more spectacular, to leave the humdrum behind, break free of seemingly unstoppable forces (gravity, society, money etc), they're really only about my wanting to be a man. Who would want to be a woman, anyway? bah.
