I can’t tell if I’m hallucinating, I’m hearing tapping and scratching and I’ve heard this quite a bit especially in my previous living arrangement. I always thought it was rats in the roof but we don’t have any, now I’m hearing it in the walls. I also have this common experience of kind of like a conversation with myself in my head although it’s kind of surprising that I find unexpected thoughts or answers from it. I’m not sure whether they’re thoughts or hallucinations either…
