I am not sure what it is because I have other issues as well but I can definitely relate to this. I will feel like people are only real when I can witness it. Sometimes I will also be talking to someone and they will tell me a story and I think that it seems like they aren't working hard enough to convince me that they are real outside of me. If a story seems cliche or boring, I just think the writings off for this part of the game.

I generally feel that I specifically am the NPC and more of an idling background one than anything else, I do feel like most other people, aside from people who have a specific type of energy or im very close with, fall into that category too but they're more "useful" NPCs with helpful dialogue or jobs or whatever. But even if I have a job/something to contribute I feel like the NPCs that have a job title not still arent really intractable. I think it's tied into how much empathy you can feel for others, which is actually an ADHD thing, many neurodivergent people have atypical ability to feel and process empathy which could negatively impact your social interactions. I compensate with compassion

I clearly struggle with this. I have to consciously tell myself they are functioning adults who have an ongoing life outside of what I see so that I can remain sane and compassionate.

Not sure if this is the same, but I used to think of it like we were all dolls in a dollhouse and basically everything we did was because somebody was playing with us making us do everything. It got real deep when I would have a dollhouse and all the inception started

Wow didn’t realize this could be an ADHD thing.. my husband and I both have it and discuss this topic all the time.

My ex once told me that when he was a kid he thought things paused when he wasn't there. Like nothing happened without him. He was always confused when he went to visit his grandparents and they weren't in the same spot they had been when he left. I didn't realize it could be an ADHD thing either. I just thought it was a cute childhood story. Interesting.

That's a type of dissociation, right? Derealization or one of those. I used to have that a lot as a kid. I literally couldn't tell the difference between dreaming and waking, and determined that the dreamworld was real and this one is just a boring loading screen between dreams. I used to tell people "It doesn't matter, none of this is real". Look up "sonder". At some point it clicks that everyone is real. Now I hve DID lol. It also reminds me of how my Autistic sister started her life journey. At first, she had main character syndrome and had no sympathy for anyone. Then a therapist explained it to her, and she was mortified. That people had real feelings like her, and she had been hurting people. She completely changed after that. I would look up dissociation if I were you!

I get a different version of this randomly where I feel like my real body is somewhere else being experimented on and the life I’m living is that experiment haha such an odd thing to experience for sure

Me, and my husband validates it and says he feels like an npc and that it makes sense that I’d be the main character. Doesn’t help lol
