I’ve thought that before. I used to think a couple of members were thinking of me when they wrote their posts. Not that they were saying anything specific I just thought their posts were related to me. It seems funny now, I haven’t thought that in a long time.
To this day, sometimes I think that random talk is about me. For example, neighbors across the street who sometimes heard me screaming, or worse. When I was delusional, I also searched for hidden signs or messages in random bits of information or media that I encountered.
Suspicions and thoughts that were similar to what you describe were never an overriding obsession in my case. Still it did happen to me. This is something that you just have to ignore and endure.
