A Dream Catcher is a Native American piece of craftwork consisting of a small hoop covered with string, yarn, or horsehair mesh and decorated with feathers and beads and believed to give its owner good dreams.

Some Native Americans believe that a dreamcatcher possess the ability to alter a person's dreams. According to Terri J. Andrews, "Only good dreams would be allowed to filter through . . . Bad dreams would stay in the net, disappearing with the light of day."

Ultimately, Good dreams would pass through and slide down the feathers to the sleeper.
