What I See is All in My Head

Honestly, everything is in our head. Seen by our eyes, sent to our brain, flipped right-side-up, and analyzed in moments. What we see is subjective. No two people, or any other organism for that matter, see exactly the same. Variables, from physical to mental, effect what we see. No matter what we see, people not only see it differently, they may come to a different conclusion and may act differently on this information. That's a part of being human. I get you probably see I could go on about this, but the gist is; really, everything is subjective.
