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 once had a lucid dream, or dreamt that I had a lucid dream (PIME TARADOX - I can't tell). I was aware that it was a dream, but was that real awareness? I was doing strange things and didn't jump straight into sex, so I don't know if it was me.

Anyways, I was with my family in some shop in a park and I called my old man. I was about to ask "How does it feel to know you are just a product of my imagination?", but I didn't because I thought it was too cruel. What do you think?
