I think it's specifically social anxiety as understood through the lens of poor theory-of-mind.
I've heard people describe feeling like they're actually the main character or that others never fully seem like 'real people' to them despite intellectually understanding those feelings to not be true. That sounded like different people making similar observations about how ToM fails them at times. These sorts of failings aren't always on a conscious level that one can identify and articulate though.
Even if one intellectually understands that they're not always going to be the centre of attention if they struggle to integrate that understanding into how they intuitively perceive social situations they're going to be prone to incorporating small inaccurate perceptions into their understanding, say like feeling like everyone is always watching them. This would be far more likely if it actually is true sometimes (like they're awkward and unintentionally draw attention to themselves).
Depending on how often and how deeply those inaccurate perceptions are incorporated into one's understanding of their life they could even potentially contribute to the development of actual delusions. One who is able to consistently debunk those perceptions would be less likely to have them start to form into delusions; one who isn't, or who sometimes has them reinforced would be more likely to go in that direction. Environment and social supports might play a role, the same person could have different experiences at different points in their life.
Not that I've ever had to apply any of this to my own life.
