"the sky had almost completely faded into darkness, the stars shone and the moon looked brighter than she'd ever seen it. She couldn't make out the sheep clearly any more, they looked like dark otherworldly beings and the crystal waters of the dew pond, usually so clear and inviting, now looked sinister and dark- like an abyss, a black hole- she was afraid to fall into it..."
