I have aphantasia, and I have specifically invoked lucid dreams. I use the SSILD method (which stands for senses induced lucid dream). I have no ability to visualize during the waking state at all, but I do obviously remember what I see during the day. When I have lucid dreams, they are visual, and detailed. They can be blurry, but there are techniques to increase their clarity. I specifically examine closely what around me when I realize that I am dreaming, and that tends to make things more detailed. In fact, my dreams are visually more detailed and clear than in my waking life, because of my failing eyesight. There are other techniques people use, such as spinning around quickly or simply asking loudly for clarity.

Aphantasia seems to be a defect in (or a difference in, I don't know) one portion of the brain whereas dreaming seems to use a separate portion of the brain. I can also see images when I'm between being awake and asleep, which seems to be related to dreaming. I've had a couple of dreams where I've successfully used the WILD technique (wake induced lucid dreaming) where you use hypnagogic imagery to create an environment and (if you're successful at it) go directly from being awake to being in a lucid dream. It's an experience that will lead you to believe that you do actually visually experience your dreams, since there was no apparent break between lying on your bed and entering a dream. I've also watched a dream fade before, and woke up immediately afterwards with no apparent loss in consciousness.

You don't have to believe me, of course, that's up to you. I'm as surprised as anyone that I can visualize while dreaming but not at all when I'm awake.
