The dream catcher originated in the 18th century. The Indians used it to capture beautiful dreams and make the nightmare disappear under the sunshine. They believed that the air at night was full of all kinds of illusions, and only the dream catcher could filter them.There is a hole in the middle of the net. It is said that only good years can pass through the hole and flow down the feathers, while nightmares will be trapped in the net and disappear without a trace with the old light of the next day.
