On 31st of October, it was a day that the Celts who are native people in Ireland believed that the boundary between the world of a living and the dead were connected. The spirits of the dead will come out to find human to haunt so that they can live again. People have to find many ways to prevent it. The Celts will turn off all the lights in the house and make their house cold, so that the ghosts will not like it.
