when you try to find the thing that experiences reality, what do you think you’ll find?

Grey goo, a network of neurons, a brain. You can literally inject chemicals into your body that change your emotions and consciousness. Physical things can interrupt my consciousness, so why would you assume consciousness is not a physical phenomenon?

When I look through a microscope, photons go through the lens of the microscope, then similarly go through the lens of my eye. My retina absorbs those photons and translates them into action potentials a.k.a. chemical/electrical signals. Those action potentials reach my occipital lobe (going through some synapses as purely chemical signals) where they interact with other action potentials from other parts of my brain, and I have the experience of seeing an image.

If my occipital is not the final destination of these signals, then what is? Where does the information go after it's processed by my brain?
