Dreams of Flying

[Nature Boy]

I've been experiencing some bizarre lucid dreams of late that involve me flying over locations I know in real life. They are most interesting. One of my dreams saw me needing to get from point A to B which were about a mile apart. It started off with me on top of a roofless double-decker bus (something I've never been on) and then I just jumped off and started floating in the direction I wanted to go occasionally bouncing off the ground in order to build momentum because it was faster.

Another dream featured me having sex, but for some reason, every now and then I would just pull out and begin to bounce off surfaces and float around my house like I was in zero gravity.

Now I know certain dreams indicate certain mental states e.g. dreams of teeth falling out indicate anxiety or stress; but does anyone know what flying dreams are about? I would love to hear some people's theories on this. Any Freudians out there who know what this means?
