My father always used to tell one of his dreams, because it somehow seemed of a piece with what was to follow. He believed that it was a consequence of the thing's presence in the next room. My father dreamed of blood.It was the vividness of the dreams that was impressive, their minute detail and horrible reality. The blood came through the keyhole of a locked door which communicated with the next room. I suppose the two rooms had originally been designed en suite. It ran down the door panel with a viscous ripple, like the artificial one created in the conduit of Trumpingdon Street. But it was heavy, and smelled. The slow welling of it sopped the carpet and reached the bed. It was warm and sticky. My father woke up with the impression that it was all over his hands. He was rubbing his first two fingers together, trying to rid them of the greasy adhesion where the fingers joined. (The Troll)
