As the literary theorists would say, the psychedelic experience is highly “constructed.” If you are told you will have a spiritual experience, chances are pretty good that you will, and, likewise, if you are told the drug may drive you temporarily insane, or acquaint you with the collective unconscious, or help you access “cosmic consciousness,” or revisit the trauma of your birth, you stand a good chance of having exactly that kind of experience. Psychologists call these self-fulfilling prophecies “expectancy effects,” and they turn out to be especially powerful in the case of psychedelics.
