Back when I was really interested in lucid dreaming, I used to get them.
Whenever I became lucid, I would look at the faces of the people in my dreams and I was fascinated how I couldn't recognize them. Like strangers living in my mind. I would also usually decide to fly, and it usually would work, but it wouldn't go on quite as long as I would have liked. I always lost control eventually, sliding into one direction awkwardly, falling into the ground.
But nowadays I never get them. I guess because I'm just not that interested in them anymore.
