I am notoriously bad at visualisation. My particular flavour of Asd+dyspraxia is fucked up KO combo. Its why I get lost walking down to the corner shop.
because I have very few qualms and desires is usually more draw to concepts and ideas rather than concrete reality + a kak early life and eastern philosophy has made me pretty laidback in my style of thinking, I usually just absorb the moment, the subject the information and let it coalesces overtime into some for of unique insight or idea, its quite handy for in the moment problem solving too because I have a database of concepts, knowledge, and past impressions to draw from as i use synthesised information to interact with new problems.
what I wrote before actually answering the question
The average person does a combination of all of them, either at the same or selectively, like in a conversation(or art or playing) you've already entered a zone/the moment/fuege state and won't be consciously doing any of the above unless your either preoccupied, brought out of it(tough questions, accusations, shocking revelations) or you're plotting something. texts your more likely to actually think about things consciously rather than just relying on your subconscious drivers to do it in the moment but that flies to the wayside when your arguing, then the chemical imbalance from the stimuli will force you to rely on in the moment replies.
got side tracked but some people dont even have the ability to think in these ways, i knew a guy who didn't have an imagination, literally. my guyss for these phenomena is that the brain either git damaged or didn't develop the typical way, i say this because verbose thoughts are actually caused by the same part of the brain as speech and its really just talking without your brain sending the signals to the pars of your boys responsible or it.
Also, the gobbledygook language you mentioned is your subconscious, everybody's mind does that 24/7 its just that usually your either distracted or cociously thinking so you don't notice, if you meditate and practce mindfulness youl actually start to notice and silenece it and you become more i control.
