Dawn is perched on a fence bordering the bluff, staring out at the ocean. It rolls over the beach many feet below. She gets up and walks to the edge of the cliff, looks down once, then throws herself off. Except she hasn't left the fence. She wakes with a start to find this was only a terrifying dream. Over the next couple days, she is plagued by other harmful visions. Are they caused by something within her? Or without?
