If the great mix-master in my head isn't going full blast it seems to me the last story in Jack Vance's THE DYING EARTH was s one of the most bizarre I remember reading. Don't remember the exact details but I could hardly believe what I was reading. Reality turning upside down in his short story "The Men Return" shouldn't fail to entertain the psychedelically inclined. And William Burroughs's THE NAKED LUNCH might spark you plug.
