I consider myself good at visualizing form and space, but when people say they "see" something in their mind's eye, I assume they're not like literally having a full-blown DMT hallucination where objects appear solid and indistinguishable from physical reality. The "images" are part information. You can think about the shadows or the highlights and they'll pop out or recede as you think about them.

I actually have a thing where I can't process math without seeing geometry in my head. But I was never naturally good at perfectly visualizing real world objects. Instead of math and code, which came naturally, I pursued art college because I considered it a weak spot for me. And indeed, I wasn't very good at it... but years of classes and practice made me better, and strengthened my visualization skill. I think it can be learned and exercised, like any other part of the brain. Just like musical recognition can be learned, if not perfect pitch.
