I saw around us a ring of wolves, with white teeth and lolling red tongues, with long, sinewy limbs and shaggy hair. They were a hundred times more terrible in the grim silence which held them than ever when they howled. For myself, I felt a sort of paralysis of fear. It is only when a man feels himself face to face with such horrors that he can understand their true import.
– Bram Stoker
Dracula, Chapter 1. Jonathan Harker, during his carriage ride to Castle Dracula. He becomes aware that the woods along the road have taken on a sinister character and he is spooked by the wild howling of demonic-type wolves which live there.
