I can never control every aspect of my dreams, only the actions that I take. So it's pretty much like the real world only with fish that walk and wouldn't miind having me as a quick snack.

My control over myself is amazing though. I can sometimes even endow myself with powers to do things. Usually my subconscious gives me a task (get people over glacier) and I have to find a way to solve it. In that scenario, if I concentrated really hard, I could move the pieces of the glacier.

So, is it control or awareness that defines a lucid dream?
