Here is an interesting and detailed account of a clinical psilocybin ‘trip’ taken by a 27 year old leukemia patient who had suffered through years of traumatic chemotherapy before undergoing a clinical trial of the effects of psilocybin:
“‘Good luck,’ Ross said, handing Fernandez the pill, which he washed down with water that he drank from a large antique chalice. Then he slipped on the headphones, put on a face mask to block out the light, lay down on the couch and waited.
About an hour later, as the drug began to take effect, the blackness inside his head turned into an onrushing cascade of white dots that swiftly morphed into a kaleidoscope of geometric patterns – gears, stars, triangles, trapezoids – in all the colours of the rainbow.
He started to hear an insistent voice in his head, telling him over and over: ‘I’m going to show you what I can do.’ Fernandez slowly suspended his skepticism and reluctantly surrendered to the experience. What he perceived to be his spirit guide took him on a Marley’s ghost-style journey, with stops at his own funeral, a hellish place littered with skulls that smelled of death where he was in excruciating pain.'
