A dream catcher is a Native American symbol traditionally used to protect against bad dreams and negative spirits. It consists of a circular frame with a woven web in the center, often adorned with feathers and beads. The web is believed to trap bad dreams, allowing only good dreams to pass through and descend along the feathers to the sleeper below. Invoking the energy of a dream catcher promotes a peaceful and harmonious sleep environment, provides protection from negative influences, and enhances mental clarity and emotional balance.
