Sounds to me like you have maladaptive daydreaming disorder, welcome to the club.

I have stories lines spanning decades of my life. When I used to watch TV, I would leave in the middle of movie or show to do what my family lovely called "vovo", names after the sound I used to make as kid, of explosions and stuff

God, there is so much could tell you. Like the fact that for the longest time I didn't identity with my own face, how my ADHD plays into this. How my imagination isn't just stories lines but Ted talks and game play and therapy and so much more. That while my sister has it, I didn't know until recently, that she doesn't do the pacing and jumping you and I do. That I can't watch, most of time, live action stuff with real people and mostly watch animation and cartoons.

I once caught myself in the mirror while daydreaming and my brain couldn't process it. I was a spectators in this world, my daydream where the real thing.

Its not as intense as this for everyone, some people are immersive daydreaming, where the daydreaming is just a hobby and not an addiction for them.

There is writers blocks, avoiding mirrors, plenty of mdds suffered child abuse. There are studies on mdd you can find. People use music. You steal ideas from shows you watched. You play scenes for days to get it just right. You feet hurt but push through cuz you are so energised and inspired.

There is a subreddit r/maladaptive daydreaming and discord server and Facebook group.
