Among the North American ogibulis, such a beautiful legend has been spread. Long ago, the local newborn babies were often frightened by the devil when they slept. Because of nightmare, many babies died. An angel learned this and began to rescue them by hand to drive out the demons and make the newborn babies sleep. However, with the increasing number of new babies, the angel is a little bit of a lack of skills, so she teaches the mother of the newborn to weave a Dreamcatcher. As long as she hangs the net on the bed, it will stop the devil from coming in, so the dream net has been spread down.
The unified Dreamcatcher is made up of branches into a circle, wrapped around the circle with leather, and then a net is formed in the circle with the rib line. Sometimes, some colored beads are worn on the rib line, and the end of the circle is covered with some feathers in leather. There is a round hole in the middle of the net. It is said that only a good dream can pass through that hole and flow down its feathers. The nightmare will be trapped in the net and disappear with the sun the next day.
