I think I have a concept-image map in my head; to test it out, I'm thinking of random words, and very well-defined images are popping into my head. "Insurance" is the impression of slate grey followed by a view into a 90s corporate office room. "Propulsion" is the bell of one of the space shuttle engines firing on full, but not centered in frame. "Gravity" is one of the rooms in the Adler Planetarium in Chicago. Etc. But it's harder to go the other way; if I see an image or a drawing and have to describe what it is, there's more of a lag before I can retrieve the words to describe it. It's much easier to think of other related images.
I'm thinking in abstract feelings and images, and then it feels like some subconscious part of my brain is actually figuring out the words and saying them, if that makes any sense.
It can be spooky sometimes since it doesn't always feel like I'm in control of the specific words I use
Just like how easy jQuery was to get started with back in the day, but a whole framework
