I wouldn't know, though. Been a solid 5 all my life despite being somewhat artistic and I guess otherwise a visually oriented person. It's called aphantasia, some ppl just can't generate mental imagery wilfully, same goes for "imagining" sounds, haptic sensations (warming rays of the Sun on your arm or w/e), flavors or anything of the sort. Our brains just aren't wired for that.
Some people on this thread mentioned being able to see stuff when nodding off/falling asleep. Same goes for me but I've no control over the imagery. Usually it's just a shifting face in the middle of my field of vision. Oh, and I have to keep my eyes the tiniest bit open for the image to appear. If I close my eyes it's all darkness until I fall to sleep and have dreams.
On the polar opposite end of the spectrum I've a friend who can imagine and visualize a red apple whether his eyes are open or closed. He can then proceed to rotate and manipulate the imagined object like he was using Blender.
