The Ojibwe people have an ancient legend about the origin of the dreamcatcher. Storytellers speak of the Spider Woman, known as Asibikaashi; she took care of the children and the people on the land. Eventually, the Ojibwe Nation spread to the corners of North America and it became difficult for Asibikaashi to reach all the children. So the mothers and grandmothers would weave magical webs for the children, using willow hoops and sinew, or cordage made from plants. The dreamcatchers would filter out all bad dreams and only allow good thoughts to enter our mind. Once the sun rises, all bad dreams just disappear.[2] American ethnographer Frances Densmore wrote:

Even infants were provided with protective charms. Examples of these are the "spiderwebs" hung on the hoop of a cradle board. These articles consisted of wooden hoops about 3½ inches in diameter filled with an imitation of a spider's web made of fine yarn, usually dyed red. In old times this netting was made of nettle fiber. Two spider webs were usually hung on the hoop, and it was said that they "caught any harm that might be in the air as a spider's web catches and holds whatever comes in contact with it."[5]

Traditionally, the Ojibwe construct dreamcatchers by tying sinew strands in a web around a small round or tear-shaped frame of willow (in a way roughly similar to their method for making snowshoe webbing). The resulting "dream-catcher", hung above the bed, is used as a charm to protect sleeping people, usually children, from nightmares.

The Ojibwe believe that a dreamcatcher changes a person's dreams. According to Konrad J. Kaweczynski, "Only good dreams would be allowed to filter through... Bad dreams would stay in the net, disappearing with the light of day."[6] Good dreams would pass through and slide down the feathers to the sleeper.
