Does anyone else have horrific brain fog? Like straight up cant think anymore?

I've always been a bit spacey but I dont think I've consistently had my internal monologue since I was 14 or so, [im 18 now] I am driven 100% by my subconscious while my conscious brain just loops 15-20 second long clips of songs I like ad infinitum

It's not like I'm a brainrotted tiktoker, I only spend a few hours a day on the computer browsing forums, occasionally watching youtube and I dont even have a smartphone! I am about as healthy phyiscally and mentally as one can be yet I do not think at all. When I'm hanging out with my friends I'll be totally out of it just daydreaming about something else with music playing in my head while my subconscious takes the wheel and handles all the social stuff, in all my dreams there's always music playing and so I dont even wake up with a fresh or empty mind

I gotta ask if this is normal, does everyone else operate like this? Do y'all verbally think to yourselves like in the movies? If not then how on earth because I genuiely feel like I'm dead and its starting to seriously mess me up
