Apparently you are…
“Richard Gregory, a prominent British neuropsychologist, estimates that visual perception is more than ninety per cent memory and less than ten per cent sensory nerve signals.”

You betcha. Imagine (this example is I think originally Gregory’s though I read about it in a book by Dennett) that you are standing in a room wallpapered by lots of copies of a picture of Marilyn Monroe. If you have normal vision, it *seems* to you that you see all the MM pictures simultaneously, that you *perceive* a tessellation of the walls of the room by MM pictures.
But that cannot be. You can only focus on a small number of them, the ones directly in front of your fovea, at any one time. Your eyes are constantly moving, to be sure, so you are constantly cross-checking that all the MM pictures are actually still there, but if some of them changed into a vaguely similar picture while you weren’t looking at them, there is about a 50% chance that *you wouldn’t notice*.
