Herds of prehistoric beasts stir as dawn breaks over the steppelands.
At the edge of the field, a family of early humans slumbers in a crude, animal-hide tent. A girl wakes first. She feels the warmth and comfort of thick fur blankets as the scent of charcoal drifts from the hearth. Fading into consciousness, she sees bison floating around on the ceiling, on the walls, on the floor, on herself.
She tries to touch the bison, but they are without physical substance.
