Dream catchers originate from a native American tradition. Dream catchers were intended to protect the sleeping individual from any negative dreams, while allowing the positive dreams to go through. The positive dreams were believed to slip through the whole in the centre of the dream catcher and slide down the feathers into the mind of the person sleeping below. The negative dreams would get caught in the woven web and evaporate when the first rays of sun shone on the dream catcher. Generations of native Americans have carried on the tradition of the dream catcher, one main reason being the hoop. Some Native Americans held the symbol of the hoop in high regards as it is said to symbolise strength and unity. The dream catcher is only one of many symbol that originated from the hoop.
