In my nightmare, I was running for my life from a creature that looked like a cross between a malevolent ape and a giant spider. Its enormous, hairy legs were each at least a yard long, and the arms on its two forelimbs were the size of my torso. It had no eyes, just a large mouth full of teeth, and its face was adorned with a nose that looked like a bunch of slimy, writhing worms. Its enormous claws tore through the ground as it ran after me.
