Other ways to conquer dreams is to know that you are in a dream. Believe it or not, that is sometimes very hard to do. When dreaming, you are put into a situation that seems real to you, even though its very not.
To identify if you are in a dream, one thing that will give it away is a sudden inability to activate lights, or a sudden foggyness in your vision. A big scary monster is a nice give-away too, but by then your more worried about the monster than wether its a dream or not <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />.
For me, to exit a dream (once and if I've indentified it) is to shut my eyes tight (and I mean hard, like 'till it hurts) and then open them with extreem suddenness that should flip you out of the dream (though occationnally I get flipped into another, worst dream...)
Also, if you know you are in a nightmare, and you can't get out, then always keep an eye on someone you are with and trust (if you are lucky enough to be in that situation). Separation is a one way ticket to danger.
