Everything to me is based on what you expect and what you convince yourself. So to escape you would have to convince yourself your not in a closet. Like close your eyes and just think I'm a wide open breezy meadow, feel the wind, forget about the closet, just convince your there and hopefully when you open your eyes your there.

An example (not the best) would be that I wanted to fall endlessly through the sky going through the clouds. But first I had to get up there, instead of flying up or something, I put my arms out fell backwards while thinking that I already was way up high. Sure enough I didn't hit ground I just kept falling.

For the real of why you dream about these things, I have no clue. Really I don't. I just know that we dream a couple of times each night every night even if we don't remember it. I just think our mind gets bored and has to come up with tons of things to do and happen in our dreams.
