Prehnite

Prehnite (Calcium Aluminum Silicate Hydroxide,) can give off water when heated, but can not gain the water back.  Known as the "prediction stone" among spiritual healers, prehnite is believed to enhance one’s protective field, dreaming and remembrance.  It induces serenity, tranquility, and reduces stress.  Prehnite can facilitate contact with impalpable entities,  aids meditation, and helps you to experience vivid dreams and remember them.  Use prehnite to achieve accuracy in prediction.  Gridding prehnite produces calmness and coherence.

Physically, prehnite supports kidneys, and bladder.  It repairs connective tissues, and helps gout and anemia.
