Can you form vivid mental images in your head?

Many of us can't. Personally, for nearly three decades I thought the ability to vividly experience a book this way was just some overused and extremely exaggerated metaphor - and then I discovered aphantasia is a thing, and I score close to top of its severity scale.

So perhaps it's less about your starting point, and more about describing a frame of mind some in the audience don't have, and can't relate to.

Curiously, I don't recall ever seeing this particular style of writing before, in any of the books I ever read.
