So, when I tell people about the theory of type and how the brain perceives things (and how the ability to read a written language rewires synapses in the brain and alters its structures) most people give me the "Just how friggin' crazy is this nutcase," look.
Here's an interesting optical delusion that helps demonstrate that what you see is not actually what is there (by showing errors in color processing) (grokked from John Scalzi's whateverettes). Your brain adjusts and makes shorthand images of reality. And this demonstration doesn't even touch on hardwired predispositions and cognitive spacing, let alone language processing and higher functionalities.
We're weirder than you think.
