we don't really see what we see

Like my therapist said, "we really don't know anything". It's what we perceive to see and know. Very subjective but very real for us as individuals.

What you see here are multiple exposures or photographic composites. Just like the movies using CGI to make the unreal look very real, our world is somewhat like that.

I have coined a phrase for this. I call it epistemological dissonance. How exactly do we know what we know? And how much does it bother us to realize that we have been disillusioned especially after the pleasant experience of being willfully disillusioned?

So, I ask, what do you know for sure?
