Stone Circle And the tears of people ran together

Quietly, he fretted over his dream. The fog of memory seemed to get thicker and thicker, the more he woke up, and the harder he tried to picture what it was he'd seen, the more it seemed to escape him. Something had left him feeling unnerved, though, so when his sister appeared he felt relieved. As though whatever it was that had frightened was something her presence would ward off. 

He smiled at her and waved his tail, inviting her to join him- but then his eyes dropped to the pale, curved bone she carried, which arched out of either side of her lips like tusks. The surprise of it made him pause. The slight aching behind his eyes, prompted earlier by daylight, intensified. He remembered, then, the curving of the shadows, the pale light of the sun between the stones. He felt something make his body stiffen. The kindness fell softly from his features, and left him with a demure, but very blank expression. His absent gaze stared right through his sister. 

The stones were white. They curved up. They were the bone she held in her mouth. Tusks. Boar-mouth.
