A dream catcher is a traditional Native American craft item that is believed to filter out and catch bad dreams, allowing only good dreams to pass through and reach the dreamer. The concept of the dream catcher originates from the Ojibwa (Chippewa) people, and it has been adopted by various Native American tribes and cultures.

The traditional dream catcher consists of a circular frame made from willow wood or other natural materials, which is often wrapped in leather or other materials. Within the frame, a woven or net-like pattern is created, typically resembling a spider's web. Traditionally, feathers and beads are attached to the bottom of the dream catcher.

The belief is that when a dreamer sleeps under or near a dream catcher, the dream catcher will capture any negative or bad dreams by trapping them in the web, while good dreams will pass through the center hole and slide down the feathers to reach the dreamer. In the morning, the sunlight is said to purify and cleanse the dream catcher, thus renewing its effectiveness.

Dream catchers have become popular decorations and symbols in various cultures and are often seen as a representation of protection and positive energy. They are commonly hung in bedrooms, particularly over a bed, and are thought to provide a sense of security and promote restful sleep.
