I also have had several encounters with the lucid dream/sleep paralysis demon before. I think I even made friends with it the last time which was the 3rd time we had met. I was driving around some old hilly country roads in this old jeep like vehicle I owned as my first car. It was night and I was just cruising along as speed. Hitting hills and getting that thrilling sensation you feel in your gut. I realized I was in a dream and that's usually when sleep paralysis demon attacks. I looked into my passenger seat and there it was. It didn't attack me though. We sort of just, hung out and cruised around a bit until I woke up shortly after. It was pretty neat.
