Dream catcher thigh tattoos have become increasingly popular among women in the last few years. The dream catcher is a traditional Native American object that is believed to protect the sleeping person from bad dreams and nightmares. It consists of a hoop, which is woven with a net or web, and decorated with feathers and beads. The dream catcher is hung above the bed or near a window to catch the bad dreams and let the good ones pass through the hole in the center.
