A description of the experience

From Paul’s blog

Way back in the 1980s, I experienced a dramatic hallucinatory episode. It was at a bad time in my personal life and friends had come to visit me in my Welsh cottage to help me through it, and they thoughtfully brought large amounts of dope, cannabis, with them. Late in the evening, I lay down on the floor near the open fireplace. The log fire had burned down into bright embers and I stared into their comforting and warming glow. As I gazed at a coruscation of gleaming points of firelight along the edge of one ember, I was suddenly presented with a gold-orange landscape spread out before me. Now, please understand me: we all readily see faces, castles and other forms in glowing embers, but this was something markedly different. As I looked, I saw trees and fields and a country lane. A cottage stood alongside the lane; I saw its door open and an elderly man come out and walk to the garden gate, open it, and start walking up the lane. Apart from the fact that the scene was in reds, oranges, yellows and golds, it was clear and distinct in the most minute, precise detail. It was like a miniature 3D movie, and it was becoming more intensely “real” all the time. Realising I was pretty high, I pulled away from the fireplace and went up to my bedroom where I sprawled on the bed. I lay there and heard the rain falling against the window pane, a sound that transformed into the flawless rendition of singing angelic voices. My entire sensory apparatus was in freeform, and I drifted off into sleep to the sound of a heavenly choir.
