Is daydreaming part of BPD?
Hi, I was recently diagnosed with BPD and I don't really undertand what is going on with me and my psyciatrist isnt really great about answering questions. But I have had a problem with daydreaming for as long as I remember, and have had one that has been ongoing for about 5 years. I like made up a character and I keep putting him in different situations, and then constantly daydream about him in them for days, weeks, or months depending on the situation. It has really hurt my ability to focus in school and I cant sleep because of it. It also dictates the music I can listen to because I can only listen to albums that fit the vibe of the story line. I also cant read a book or watch a movie without losing focus by daydreaming a situation where the character enters the story. Sorry is this is a stupid question, but I was wondering if this is part of BPD. Thank you.
@energeticMap9646 Hello! Sorry to hear your psychiatrist isn't answering your questions, sometimes it's hard when we don't feel understood. And it's not a stupid question, it's good you came here and asked!
Seems what you are experiencing could be Maladptive Daydreaming - where your mind takes confort in an imaginary 'world'. Daydreaming in that way can affect a person's life and make it hard to do day-to-day things, like it seems for you with not being able to focus (that's why it's called "malaptive"). It's not exactly a part of BPD, and there's still a lot of research on the behavior, but it's something that can happen in people with BPD.
I've read it can be a type of dissociation, and for me it does feel like it. When things are difficult, I'm struggling or feeling alone my mind does go into that 'world', and it's like you said - listening only to music that fits the story, and it's difficult to do certain things. Dissociation is a part of BPD, though. Also, maladptive daydreaming is said to be a coping mechanism of the mind and can happen with many disorders or even due to childhood trauma. Basically, your mind cannot handle something that's difficult and creates this alternative world or persona that you go to, so it distracts you from the difficult things. But it's subconscious, so it's not something we feel we have control over, not like 'regular daydreaming'. You're not alone in this 
I have never come across any suggestion that daydreaming is part of BPD—not in anything I've read about BPD, not from any of the people with BPD I've known in real life, and not from any of the professionals I have met. Most people, I think, would say that BPD is more about intense and unstable emotions. Its other official name is emotionally unstable personality disorder.
Very focused and persistent daydreams like the ones you describe sound like the way some authors describe their intense need to write.
If you feel that your daydreaming is the most significant problem in your life, I wonder what made your psychiatrist diagnose you with BPD.
