Curious to know from the people who have read a lots and lots of text or books or watched movies.
The more you read or watch the faster this becomes.
The neat part is when you can do a double or even triple reading near instantaneously. It’s a little trickier for films, but still possible. I believe this is how your friends who are really good at just breaking down meaning on first watch are doing it —- they have gained media literacy skills that let them take in scenes in a blink of an eye.
Practice your memory, and you can also hold past scenes in your head as new scenes come up. New connections made there too.
Once I get started on a piece of fiction, I don’t exactly see the text anymore either — my brain starts constructing a sort of movie/diorama in my head and every subsequent sentence builds it more and more. Makes reading fiction great and emotional/symbolic analysis great but funnily enough makes me a weak analyst of the language and craft itself. Made my years in undergrad ironically challenging.
