Schrödinger's cat
The whole idea that if you deliberately make the brain malfunction it will somehow work better - by "expanding your consciousness" or whatever - is just so bizarre. When something malfunctions the results are never better than when it's working correctly. The brain evolved to provide an accurate understanding of its surroundings to its owner, hallucinations (whether the result of mental illnesses such as schizophrenia, oxygen deprivation by centrifuge or other stress, or the ingestion of class A drugs) are neither informative nor desirable.
