I actually had a LD first before I knew what it was. When I was a teenager, I had a really intense dream that I had supernatural abilities, and the CIA were chasing me. Near the end of the dream, they shot my dad on our lawn outside my house. I remember thinking I didn't want to see this plot through, I didn't want this to happen or deal with it, and it was like the scene rewound and I thought, "Oh wow, this is a dream!" and told my dad to get inside the house.

That dream prompted me to keep a dream journal, ever since then. I tried doing some research on the internet and found that dream control has a name, but I couldn't really find much else about it (this was about 12 or so years ago).

I'd sporadically had LD's since then, but never had very much control over them. Mostly just that I knew I was dreaming. Sometimes I only had enough control to make plot choice changes or scene changes. Sometimes I had enough control to activate certain abilities (like one dream I was in someone's house, and I didn't want to get caught, so I levitated), sometimes I had total control to stop the dream plot and do something cool like flying, only, I wouldn't get very far with that. I could get up there, and I kept getting dragged back down, while in flight.

I found DV through a google search too when I wanted to learn if I could have more control of lucidity.
