I can't consciously form mental images, but I have no problem daydreaming images which seem to come to my mind randomly, and I do sometimes have vivid dreams.

I have something like this experience. I can visualize schematic or geometrical images pretty well. But when it comes to textural detail, one thing slips away when I try to visualize the next. I can visualize a wagon wheel spinning in space, but if I try to add the grain of the wood or gradients in the lighting, it doesn't work. I can visualize a green lawn as seen from high above, but if I try to visualize the different blades of grass as they'd appear at standing height, I can't hold onto the details.

But all this changes when I'm dreaming or about to fall asleep. In fact, one way I can tell that I'm about to fall asleep is that I find myself able to visualize that lawn, or many pebbles at the bottom of a clear brook, or other such texture-rich visual tableaux.

ETA: In the couple nights since I wrote this comment, I decided to try inducing sleep by forcing myself to visualize things like grass and pebbles in detail. It seems to work remarkably well. I've stopped taking the melatonin pills that I'd been relying on.
