I had a dream, where I figured out it was a dream and was lucid dreaming, but then it turned out that I was dreaming that I was lucid dreaming. I don't remember anything else that happened, except I think it was at school.
I also used to dream about redoing the last day of school, as in making different choices. My best friend was leaving, and in the dream I made a different choice from in real life. I woke up right after I made the choice.
