During what Americans would call middle school (unsure of the British term for this, I'm bad at school terms), age 13-15, I had recurring nightmares of being trapped in the school building. Every time I tried to walk to the exit, the doors would lead to different places (a first floor door would lead to the top floor science classroom, etc) and I couldn't find my way out. When I got into proper high school I stopped having those dreams as I was no longer in that bad enviroment.
In my dreams, I am almost always physically male. I've had these recurring, very realistic dreams in which I wake up on a hospital bed and am male-bodied, I look just like a cis guy, and I'm filled with happiness. These dreams I've had since I was 11 or 12, about twice a week.
Currently my dreams revolve around being absolutely terrified of going up to the attic. I have to stop at the attic door because I am so scared I cannot move. It's a recurring dream, I have it about once every week. Another recurring dream, once every other week, is about being drowned by strangers in an area I've previously regarded as safe (my home, my current school, my old psychologist's office, etc).
