For 500 years, dream catchers have been cultural symbols of intrigue worldwide. The most common folkloric design is a 12-point dream catcher. According to Native American legend, the first dream catcher was woven by a “spider woman” to catch the bad dreams of a chief's sick child. Once the bad dreams were caught, the chief's child was healed (Oberholtzer 2012). The basic design has been used for 500 years and is similar to the weaving of a spider's web.
