I recently read a study based in experiments which said that contrary to the idea that psychedelics make the world unfiltered and open up the brain to more information, what they actually do is the reverse. Psychedelics reduce information, reduce sensory input, and as a consequence the brain fills in the gaps via hallucinations.
