My gut feel is that people's experiences can be quite different. V.S. Ramachandran's books have nudged me to take these things more seriously.
I think visual imagination is also related to spatial rotation abilities. For example can you imagine yourself in your hometown, then imagine an "animation" as you (from a first-person perspective) fly up vertically, then turn in various directions and sort of feel where the landmarks are in the mind's eye? Or does that sound nonsense to you? Would you agree that being faster at certain tasks (that require a visual scratchpad - e.g. imagining a tabletop and being told what happens e.g. add a triangle on the left, add a square halfway overlapping the triangle etc) indicates that someone has more vivid imagination?
