In some Native American cultures, a dreamcatcher is a handmade object based on a willow hoop, on which is woven a loose net or web. The dreamcatcher is then decorated with sacred items such as feathers and beads.
For me they are beautiful decorational items, but with a meaning, a sens. It can stand for different things for different people and no dreamcatcher is ever the same.
You have a million colors and sizes, decorated with various different items so just pick the one that speaks to your soul and personnality.
