In Native American cultures, a dream catcher is hung over the bed to offer protection from bad dreams and nightmares. My interpretation of that is to wear a crystal bracelet with a feather dream catcher charm, to protect us from our negative thoughts and to catch our dreams and wishes and help make them a reality. Turquoise stones offer tranquility, protection, good fortune and hope. Moonstone brings calmness, stabilising the emotions and helps us to manifest our dreams and desires. Purple Sea Sediment Jasper protects you against negative energies as well as easing emotional stresses and conflicts. Blue agate is known for its calmness lessening negative energies, releasing tension and helping you to relax. Howlite is said to aid insomnia and calms an overactive mind.
