In today's conclusion to a weekend workshop that Terence McKenna gave in early October of 1992, he gives the reasons that lead him to not believe that extraterrestrial, self-aware life forms have visited the Earth. Even after describing the vision he encountered in the jungle during his 1972 experiments at La Chorera, he refused to believe in alien encounters other than with mushrooms. He did, however, say he believes that information from the future is being reflected back into present time in the form of UFOs. Terence then concludes with some excellent advice about how to use psychedelics, which he prefaces by saying, "I am terrified of psychedelics. I never take them without a sense of sickening dread."
