Does your inner voice get too loud?

I dont hear voice or anything its my thoughts like i use alot if inner voice ( self talk, daydreaming etc). And sometimes i have feeling my thoughts get so loud. I also have ocd ( main theme is fear of schizophrenia) so i will start to observe my inner voice etc. Could i be just hyperaware of my inner voice?

And i have song stuck in head most of the day. I will hear a song and it will replay for hours in my head.
