I've been an on-off lucid dreamer. As in, I've gotten interested for 2 weeks, the quit because I was too busy or was too lazy.

Today, I got my first lucid dream. It was me and a friend in an amusement park. We decided to do something wild, so we decided to steal truck. We run in, and lock ourselves in. The woman who owned it started yelling at us and threatened us with a knife.

Bam! I realized I was dreaming. "You can't hurt us! It's MY dream!". She kept raving on about how she was going to cut us, so the completely unpredictable happened

"GET THAT $#% OUT MY FACE %#$, I'M THE JUGGERNAUT %$#&!

The rest of the dream comprised of me ruling the world.

I was totally surprised about it because I had no premature awakenings, no false-awakenings, and didn't have to spin or anything.
