I don’t mean songs that are catchy and your singing them to yourself. Just to give an example the sound of my dad‘s cane hitting the wood floor gets stuck in my head and it repeats the sound when it’s not happening like right now my dad is not at my house and yet sometimes at night I can hear his cane hitting the wood floor as if he’s here. It’s kind of freaking me out a little I just wanted some tips on how to get rid of it.
