It does kinda make sense, I get these intrusive silly random thoughts sometimes. This one time I had the silliest song lyrics stuck in my head for two weeks! They were about the color azure. Silly. They got so loud, as if someone had turned the volume on the radio way up and would totally interfere with my thoughts. Ugh. I was suffering from severe anxiety at the time, don't know if that's related.
Then last night I noticed I sometimes mentally repeat random words like a broken record. the last thing I thought before falling asleep was about how encouraging it is that many people do better with treatment and the last few words were "from hell to well". They're positive so I don't mind but am wondering whether that's a symptom of some disorder. I do think mental repetition is more of a subconscious attempt at pacifying oneself. The intrusive loud thoughts are more annoying to me but as long as they're not very negative ones I can live with occasional bursts of silent gibberish. Really wonder what it is though..
