Native American culture prominently features dream catchers to gather good dreams and do away with bad dreams. The reason comes from the story of Nokomis, the grandmother in Ojibwa folklore. Nokomis watched a spider weave its web day after day until one day her grandson came in and tried to kill the spider. She protected the spider and, in return, the spider went to the window and spun a fresh web in the moonlight. It told Nokomis: See how I spin. See and learn, for each web will snare bad dreams. Only good dreams will go through the small hole.
