Inherently though, aren't we biased to only think that which we know can exist? What do the colors we can't see with out physical eyes look like? Surely, there is a creature in a place somewhere having a wholly different experience to the point where if were to experience a day behind it's eyes, you would think it total fantasy. If everything is a possibility, there is a realm where I have one eye, two eyes, three eyes, four eyes, one where I am an eye, one where I hear through my eyes, so on and so forth.
Basically, not all realities would have to conform to our expectations of logic since we can't really fathom infinite possibilities.
Good point.
