Lucid Dreaming

I'm not sure how to achieve the actual state of lucidity, but once I realize I'm at that moment, I can have a usual decent control over my dream. ie- Flying around, changing things, etc.

I found that if a certain thing happened that day, or major things you've been thinking about, usually affect the state of your dreams.

i heard a tip that if you see something like a clock or something else that has numbers on it in a dream, and look away and back at it, that it wont have the same numbers, and that can be a cue for recognizing its a dream.  maybe im weird but numbers are consistent in my dreams.
