Indeed it doesn't directly see the world (otherwise we wouldn't need
eyes and brains), but what is "seen in the brain" can without a problem
be called an internal representation, at least if you assume that it is
a pretty correct one. When you see a car coming right at you and it
crashes into you.. and you wake up in a hospital later, the internal
representation that told you there was a car crashing into you was quite
a correct one. (as opposed to for instance dreaming an accident)

I would think that the brain certainly creates its own reality - an
experiential reality which is body-brainprocess.

Maybe without the echo-box of language: "I know that I know what I
know.." there would be no self-awareness?

Maybe the I ("self") is the conscious evaluation between the known and
the possible, in as far as it serves the organism to function and
survive. The duality would be the past-future duality. The unknown is
the "now" - it might not even exist!
For poetical purpose only:
"Being rides on the crest of becoming"
(source UNKNOWN :-)
On consciousness: experiential bubbles,
solipsism, mind-brain duality, the binding problem,
the hard problem and artificial consciousness.
