We walk on earth in the shadow of a mystery nature. Among the crossroads, one of them is on a stopped door whose sign announces the colour: “The Psychedelic Experience”. A delightful lightning for some, a vicious journey for others. A strange experience that, it seems, once opened a monologue between our ancestors and the mystery. Since then, hallucinogens plants that are the support of this apartment have been bourling in history as a blasphemy that is always punishable by prosecution. What defamation is it? The one to name God's names? What is His epithetes? Magic fungus? This is tempting: to assimilate the Divine with the effects of a plant. Only, beyond this legislative stimumpfery, something much more serious awaits us. A rarely reported thing like the Other, the Saint Other, the Logos or Alien… It is indeed the story of a drunk not like others.
