We're All Hallucinating All the Time

"If hallucination is a kind of uncontrolled perception, then perception right here and right now is also a kind of hallucination, but a controlled hallucination in which the brain's predictions are being reigned in by sensory information from the world.

In fact, we're all hallucinating all the time, including right now.

It's just that when we agree about our hallucinations, we call that reality."
