Skull face 

The horror first took concrete form amid that most unconcrete of all things—a hashish dream. I was off on a timeless, spaceless journey through the strange lands that belong to this state of being, a million miles away from earth and all things earthly; yet I became cognizant that something was reaching across the unknown voids— something that tore ruthlessly at the separating curtains of my illusions and intruded itself into my visions.
