Is it normal that my thoughts repeat the same sentence over and over?
Okay, context. This isn't something that's literally always happening. I'm not crazy, or, at least I don't think I am. Anyway, this usually happens when I'm playing a game or something that requires a degree of focus, and my brain just seems to get stuck on one sentence or phrase. Maybe it's because I get mentally worn out, but I'm no expert. Does this happen to other people?
