I originally got into it for the "mind over matter" appeal - bridging the gap between conscious and unconscious and mind and body, so that I could have more of a sense of power and control internally.

Also, it's fun to be able to fly, walk through walls, and hit on random people without consequence. There are no inhibitions in dreams except those that I expect to exist.

And a lot of real life inhibitions are probably just expectations too. So I'm now thinking that if I refamiliarize myself with the nature of dreams, and develop dream control, I'll be able to use similar principles to work around the whims of my subconscious in real life too.

I also got back into it because I wanted a good solitary hobby.
