I'm a 5 on the VVIQ. I can see the 3D apple, put it in my hand, rotate it, watch the light glint on the dimples in the skin, imagine tossing it to a close friend and watch them catch it, etc.

It's equally astonishing to me that others are different.

I can see I my head with ~80% the level as seeing with my eyes. It's a little tunnel visiony and fine details can be blurry, but I can definitely see it. A honeycrisp apple on a red woven placemat on a wooden counter top. The blue dots are the size of peas, they are stickers in a triangle.

It not just images either, it's short videos.

What's interesting though is that the "video" can be missing details that I will "hallucinate" back in that will be incorrect. So I cannot always fully trust these. Like cutting the apple in half lead to a ~1/8th slice missing from one of the halves. It's weird.

I absolutely do. For example, when I'm playing D&D, or listening to a podcast of other people playing D&D, I can "see" a fully realistic view of what is happening in my head. With the apple test, I can see a nice red apple, with the little vertical orange streaks, three blue dots arranged in a triangle, and I can rotate the apple in my head and have the dots move as you would expect from a real apple. I have a very vivid imagination

Talk to people who read a lot.

There are people who actually "see" a full-ass movie in their head when they read.

These are also the people who get REALLY angry when some live-action casting choice isn't exactly like in the book. I just go "meh", because I kinda remember the main character had red hair and a scar and that's it. :D
