I wonder if it's possible to improve your visual imagination through practice? My own mental images tend to be dim and fuzzy, far from the photorealistic scenes some people seem to be able to conjure up. But I wonder if there's a feedback effect here, where people whose visual imagination is stronger to begin with tend to use it more, thus further strengthening it, while people whose visual imagination starts off weaker use it less, and so it remains weak, or gets worse.

It would seem like learning to draw or paint might be a good way to train visual imagination. As I understand it, many artists begin by mastering representative art based purely on reference models, then later develop to produce works partly or wholly inspired by mental imagery.

I'm curious if anyone here who learnt to draw or paint during adulthood experienced a corresponding increase in the vividness of their mental images, particularly in areas not directly related to drawing? E.g. did your dreams become more vivid? Are you more able to imagine the specific details of your house, or your friends and family? Do your mental images feel "clearer" or more defined?
