I recently had my first realization that I was in a dream, no reality check, I just recognized the architecture from something I designed. The problem was that I did not have a body in the dream, I was just watching in a third person view as these two characters moved around. I had that realization for a while until the dream completely unraveled and I woke up.

I realize that in allot of my dreams I seem to have this free floating view in my dreams but cannot affect the dream itself. Therefore I have two questions; How do you attain lucidity from a camera-like perspective? i.e reality checks when you have no arms and are basically a floating camera. With most people I suppose that the whole floating thing would be a pointer but I use a lot of software that allows the user to move around like that so I hardly notice it.

If I manage to recognize that I am in a dream, like I realize I could never float around like a camera in real life, how do I keep my lucidity or attain a body?
Thanks for any help!
