I didn't read most of the site yet, but I am just wondering if I am sure what lucid dreaming is.

When I was younger, I watched lots of R rated horror movies, and I often had scary dreams. I always feared that I would have another dream because they scared me. Then somehow I learned that I could sort of take control of my dream. There is one dream that I especially remember. I was walking around in my neighborhood and there was a big truck and there was a vampire in a strange astronaut looking suit. Because I learned that I can control my dreams, I always bit my thumb to see if it hurt so I knew it was a dream. So in that dream, I bit my thumb as always, and I didn't feel anything. So I purposely walked up to the vampire so he could bite me so I would wake up. It worked, and I woke up, or at least ended the dream. So is that lucid dreaming or not?
