"Objective reality" and seeing different aspects ofeality

 Imagine how different this creature sees the world than we do. While we think of our Qualia (conscious experience) of vision as the "true experience" (how the world looks like), other species see something else.

This creature is called a Chiton;

"The creatures have developed a ceramic shell system that's not only flexible, being comprised of eight overlapping plates, but also provides high levels of visibility, by incorporating tiny eyes throughout. Unlike the vast majority of other living creatures, the chiton's eyes aren't made from protein, but are instead made up of the mineral aragonite – the same ceramic that makes up the rest of its shell."

And consider that color is not something that is even perceived by deep sea creatures. They probably see something like waves of density, which is an experience we can't even imagine.

So the qualia actually represents relevant phenomena in an organism's environment. And most likely the brain of the organism (if it has neurons) is pre-organized to receive exactly that kind of input to then shape itself to produce a particular kind of qualia.

That is why the tongue can be taught to produce the sensation of sight with the right stimuli. The absolute crazy thing about the brain is that it seems to be the type of activity it produces that will generate a certain kind of experience.
