In some Native American cultures, a dreamcatcher (ordream catcher; Lakota: iháŋbla gmunka, Ojibwe: asabikeshiinh, the inanimate form of the word for "spider" or Ojibwe: bawaajige nagwaagan meaning "dream snare") is a handmade object based on a willow hoop, on which is woven a loose net or web. These dreamcatchers are handmade, and no 2 are alike.
They are designed to catch bad dreams, unbound spirits, and unwanted things about us that we do not like. There is a cleansing spell that comes with these so you can clean it out once a week.
There is a chime placed at the bottom so every time you hear it ring, you know you have caught something in it's web.
