Yeah, I'm the same. However, I'm also very aware that not everyone thinks like that.
I'm sensitive to sounds, and most of my thinking has to be vocalized (in the background) to make sense to me. It's incredibly hard for me to read non-Latin scripts, for example, because even if I learned the alphabet, I don't recognize the word easily before piecing together all the letter clusters that need to be spoken specially. (I especially hate the thing in Russian where "o" is either "o" or "a" depending on how many of those are in the word. It slows my reading of Cyrillic script down to a crawl.)
Many people - probably most of them, even - don't need that. Those who think in pictures, for example, have it much easier to solve Sudoku or read foreign scripts. They don't need that much linguistic baggage to think. At the same time, when they write, they often struggle to form coherent sentences above a certain length, because they have to encode their thought process (that can be parallel and 3D) into a 1D sequence of tokens.
I don't know whether this distinction between types of thinking has any scientific basis - I'm using it as a crutch to explain some observable phenomena in human-to-human communication. I think I picked up the notion from some pseudo-scientific books I read as a teen (I was fascinated by "neuro-linguistic programming," which tends to list three distinct types of thinking: visual, auditory, and kinesthetic). It unexpectedly finds applications in human-computer interfaces, too, but LLMs have made it even easier to notice. While "the three NLP modalities" can well be bullshit, there seems to be something that differs between people, and that's where threads like this one seem to come from.
