You slip into a trance state
Your head is swimming. The dancers seem to have many arms. Movements leave odd trace patterns that float in the air. A loud hum fills the air. It reminds you of the hollowed out great bull horns and shells that you people blow in to produce music. But this sounds like a horn big as a hill. You are staggering, falling out of step with the other dancers. They put re-assuring palms on you as the pass, letting you know it's o k, that your entering the spirit world and to go with it. You howl and fall to your knees.
A horrid dark vision comes. Beasts that are part horse but man, tall and vicious. They attack fast and without warning while the men are out hunting. They kill all the children and old ones. The woman are raped. Some are killed but most are taken away, along with the goods, the wealth of your people. The furs the tools, the tents.
You rise up from the ground with a terror filled scream that stops everyone in there tracks. You tell the shaman about your vision. He says dark times are coming. All must prepare.
