I always get this eerie feeling that if someone has aphantasia, they are possibly also a P-Zombie.

If you cannot visualize things in your mind, and seeing is just transforming light into visual imagery, how do you know you're actually "seeing" anything? The data goes to your brain but you just process the image without actively observing visuals, you just know what's there in front of you, but as data. If you can't see visuals, what else can't you see? Conscious processes?

The analogy to use would be like an LLM's way of "seeing" an image: it describes it into words and then recognizes what it is. A human brain would just do this much faster. Aphantasiac brains.
