there's a huge difference between waking up and remembering a dream, and knowing you're in one a the time. obviously you won't be conscious to know that you were in the dream until you wake up and can consciously understand what just happened. lol You get the idea.

There's probably infinity levels of lucidity. I can understand I'm in a dream, but I can't do anything about it. I very rarely question reality in dreams. like, no matter how weird the dream is I just don't. I could see a monster truck driving down the street and not question my surroundings in the dream even if I remember consciously being awake and thinking in the dream at specific times after waking up. The difference between thinking and doing in my dreams seams as if it's impossible.
