Considering these three statements:

- the brain predicts what its upcoming input will be,

- quantum biologists ask if the human eye is sensitive to quantum effects, and

- measuring quantum information under different bases result in a different quantum state of not only the measurer, but of the world being measured.

I wonder if it is possible that the brain uses its predictive power to change the basis under which the eye measures photons, resulting in different perceptions as well as a different reality. A bit of a crazy idea but I don't see any reason why it shouldn't be the case other than if it is shown that biological sensory organs are simply not that precise.
