That's interesting. When I close my eyes and imagine "seeing" things, I would actually describe it as pretty much exactly like the sensation I have when I "see" stuff in dreams. To me, this similarity is especially clear when I wake up in the middle of a dream, then close my eyes while awake — I can continue where I left off, and it "looks" exactly the same as in the dream.
But I agree that it doesn't feel like "sight", as in the physical act of seeing with your eyes.
I think I am aphantasic or mostly so. I don't see visualizations but have vague echoes of their derived properties like spatial structures. It is almost like proprioception if I were some amorphous being that could spread out my countless limbs to feel the shape of the scene.
But, I do have vivid, sometimes lucid, dreams. I would say they are exactly like seeing and being in terms of qualia. It feels like my eyes, and I can blink, cover my face, etc. It's like a nearly ideal, first-person VR experience.
They are unlike reality in that I can be aware it is a dream and have a kind of detachment about it. And the details can be unstable or break down as the dream progresses.
Common visual problems are that I cannot read or operate computers. I try, but the symbolic content shifts and blurs and will not remain coherent.
Motor problems include that I lose my balance or my legs stop working or gravity stops working and I start dragging myself along by my arms or swimming through the air, trying to continue the story.
If I've been playing video games recently, I can even have a weird second-order experience like I am fumbling to find the keyboard and mouse controls to pilot myself through the dream! That is a particularly weird feeling when I become aware of it.
I feel like I have recurring dreams in the same fictional places, but they can have unreal aspects that lead me to get lost. Not like MC Escher drawings, but doorways and junctions that seem to be unreliable or spaces that don't make sense like the Tardis.
