So how/when did you people have your first lucid dream?

I'll start: when I was little (8 maybe), I realized that I could open my eyes in reality if I wanted to end my nightmares during the night. This meant that I had to first realize when one was occurring. The next step was to understand that I could do anything I wanted in dreams. So I ended up using special powers to fight the demons in my dreams.

So what about you?
