Sometimes when I dream I see things that are compleatly made up. Things from people to creatures to objects. Plus they get an idea of what things look like when they touch them so.
My dad often says that you don’t see with your eyes, but with your mind. I believe that they do have dreams and experience what we would call “visual” but they dont have a reference of that “visual” experience so their mind simply dont know what it is and try to compensate or “explain it” with the others senses. But that’s just my thoughts.
