I suspect I have aphantasia or at least extremely limited voluntary visualization (I can with some effort make myself feel like I'm maybe experiencing something that could be related to a visual sensation, but I would hesitate to call it imagery).

I do still see dreams, but extremely rarely. They're very different from any sort of pseudo-visualization I might be experiencing consciously, much closer to the actual visual sensation I get with eyes open. It's also much harder to remember anything about them.

Just recently I had my first experience of a lucid dream, which was pretty exciting. Unfortunately, the only thing I remember about it is the realization of what it was and then flying around (somewhere, no idea where) for a while until I woke up.

I also remember that it was a visual sensation, though I don't remember the visuals themselves.
