dream catchers are an old Indian tale. They are said to catch your bad dreams before they enter your mind and you are supposed to shake the bad dreams out of your dream catcher or they will escape to your mind. Really just an old tale for kids.
a dream catcher is a thing that the Indians used. They believed that if a dream catcher was in there home then it would "Catch" all of the bad "Dreams" when they slept. I have a few in my room but I'm not Native-American Lol.
in dream catchers their is supposed to be hole in the middle of the webbing. bad dreams get stuck in the web and good dreams pass through the whole in the webbing. the sunlight in the mornings shines on the bad dreams and they dissipate into ''nothing''. the natives who started this believed the creatirx of the universe was the spider mother. she wanted to protect people so she taught them how to make dream catchers.
