“Vision is not the raw stream of sensory input from our eyes. Rather, that input stream acts like an error-correction signal. Vision—what we actually see—is a reconstruction of the world around us, an actively maintained and constrained hallucination.”
“Suzuki et al. 2017 hypothesize that hallucinogenic experiences are … a result of heightened top-down prediction at the expense of bottom-up error correction.”
