The Ojibweg believe that making a dream catcher yourself and putting it up against the bed is nasty dreams. For centuries, parents have been making dream catchers to hang over their children's cots or cribs. It is assumed that the sky is soaked with dreams, good dreams, but also bad dreams. During the night the bad dreams get caught in the web and according to tradition they slide off in the morning and dry up in the morning sun. Good dreams can find their way unhindered into the center of the dream catcher and thus enter the life of the dreamer.
