You somehow magically sense something there through your eyes, but you don’t see it at all. It’s stronger if you don’t look at it directly and move your head about a little. It’s like there’s an unconscious observer reporting where things are, and you just take the info and acknowledge it, but you don’t see it. Anyone else get this?
One time on a red eye flight with my eyes closed behind a sleep mask, I swore I was getting that dark blue rainy grainy projection of my surroundings like Daredevil. I could see the seat in front of me, my wall, my window, and the aircraft walls ahead of me visible aboce the seats. There was even the passing of the ground outside the window. That’s where I figured out it was a false image, not some super radiation sense. After toying with a few minutes, I looked out the window to find the ground moved at a fraction of the imaginary speed. However, I do beleive it was a generally accurate recreation of my surroundings.
When you deprive yourself of a sense, your other senses can ramp up their sensitivity to compensate. Or your brain has less bandwidth than all 5 can provide at once. Either way, your perception is not as rigid as it may seem. You can remember a lot about locations in a familiar place and faint cues can clue you in. It doesn’t mean it’s accurate, though
