Yes. I totally empathize with you, as it was a major problem for me as well until a few years ago. My daydreaming had similar manifestations as yours, such as doing it while listening to music and engaging in a repetitive activity. I'd been doing it since early childhood, surely it was some sort of coping mechanism due to social isolation and lack of a real emotional connection. And a sometimes overwhelming home environment. You are not alone, although this is how it often feels like. I would spend hours daydreaming, I would make time for it even though it could impact my school performance or my daily life somehow. Thankfully it didn't, but it was distressing and made me feel alienated. Mine would also manifest as writing scenarios with the characters I had in my head, which would always involve me as a character as well. I see patterns in these fantasies, it is interesting, although they can be very distressing. There was a forum for people with MDD, I can't find it anymore, but you can check it out, maybe it can help you feel less alone in this if this is how you feel. I used to go there years ago and it helped to a certain extent. I would also stay awake on purpose to daydream before going to sleep, for hours, which made me feel wired and excited and would impact my sleep. I was still dealing with this issue, MDD, until I started getting more involved in real relationships. I would still do it before falling asleep until I formed a meaningful emotional connection with someone. It just vanished, the MDD, but it doesn't work like that for everyone, as MDD doesn't always develop out of isolation and loneliness I think. Good luck in managing this, I know it can be a pain in the ass. And feel free to PM me if you want to talk about this, maybe having someone who can relate will help.
