THE DREAM CATCHER : The plains Indians say that you hang them by the window or at the head of your bed. The bad dreams get caught in the web. The good dreams work their way through the hole in the center, rest on the feather like a dew drop, and evaporate to the Great Spirit in the morning sun. The prayer beads on the Dream Catcher trap all the bad dreams that are left on the web and then burn them up.
