Norwegian folklore says that Christmas Eve is kind of like Halloween and brings about a number of evil spirits and witches. The brooms of the houses are hidden to keep them away from witches and men will often go outside and shoot their guns to ward off evil spirits.
Pagan winter celebrations used to revolve around Thor’s pet goat and a person would arrive at the parties wearing a goatskin and carrying a goat head. He would eventually fake his death and then return to life. As Christianity started to take over the area, the goat was recast as a form of the devil and he was eventually banned.
Since then, the goat character was morphed into Julebukk, a “yule goat.” The new story of the goat involved him traveling from door to door where he would get gifts for keeping the evil spirits away. Nowadays, kids dress up and play the role of the Julebukk, where they get treats as they visit the houses.
