When dreamcatchers were originally made, the Ojibwe people used willow hoops and sinew or cordage made from plants. The shape of the dreamcatcher is a circle because it represents how giizis – the sun, moon, month – travel each day across the sky. Some consider the dreamcatcher a symbol of unity among the various Indian Nations, and a general symbol of identification with Native American or First Nation cultures. 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.
