I see what you're saying, but he is claiming that some people might literally see auras around other people. Or the other person sees a literal grid in her visual field all the time and projects meaning onto it. And that's within normal human variation. Sure you can imagine that bats or octopuses have much weirder subjective experiences. But it's still not something that's widely recognized. They would likely say if you literally see auras then you must be a crazy, non-functioning person, when really it's just a quirk of your perception that is invisible to everyone else.
