I can draw sort of ok, but only because I've practiced a bit. I can visualize quite well, I assume because of some innate ability + I practiced extensively as a child for fun. It is definitely a skill that requires focused training, at least in my experience, so it makes some sense that the average person wouldn't spend too much time going out of their way to practice. If I get out of the habit for whatever reason, I'll slowly lose proficiency at quickly and easily picturing objects in near life-like detail, manipulating them skillfully, rendering complex scenes, holding images with eyes open or under distraction / activity, etc. Objects will start off grainy/foggy by default and only clarify if I really can focus. Scenes and large complex objects will be much harder to hold together as a whole with distinct parts/areas. Changing an object results in more fog or losing the image temporarily. That kind of thing.
