Not sure if this is the right place for this but:

Sometimes I'll get random, repetitive thoughts stuck in my head, they'll just repeat over and over and over for no apparent reason whatsoever. It's almost obsessive, but it's frequently completely random and not necessarily connected to anything important. They aren't psychotic thoughts. They're just thoughts, sentences, lines. Sometimes I'll get emotional from it, though, depending on the associations I wind up making in the background. Sometimes I'm screaming at myself on the inside to stop.

Another strange thing I'll start doing is I'll out of the blue start counting my steps in my head as I'm walking. I realize I'm doing it in the middle of it, almost like I'm waking up to it, if that makes any sense. I have no obsession with needing to know the amount of steps I take, yet it seems to just happen, almost like some involuntary compulsion.

Do things like this happen to anyone else?
