That's spooky. But, it also goes to show that the human brain is far more complex than any of us can imagine. Understandable, considering who designed it, huh? Better'n IBM, Apple and Microsoft all rolled into one.
I heard it explained thusly (yes, I watch Good Eats): The normal sight we use day-to-day is advanced, high-tech stuff. But there is a more primitive type of sight, one that only picks up motion. Back when my g-ma worked at the local university, she knew someone with this sight. She tried to warn her that she was approaching a tree and got a sharp, "I know, Peggy. I can hear it!" I suspect it's the same sight I use to stay on the road when I'm day-dreaming while driving.
This is kinda in my story, Epiphany. One of the main characters is blind, but he sees things that no other human does, far beyond the veil.
