My mother complained of hearing moters in her head for years, once she started losing her hearing. I worried about that….you know, something silencing my ever rich inner personal dialog.
I’ve got an entire soundtrack going on in my head. Every piece of music I have ever heard just pops up, unbidden and reels out. Stuff I didn’t even know I knew. Classical stuff (I took music classes in college and obviously have entire catalogs of the stuff waiting in the wings.)
The entire Beatles catalog. Everything Johnny Cash ever sang, apparently.
