Grape Agate is also known as Botryoidal Chalcedony.  It is a stone that encourages lucid dreaming for prophetic messages.  When Grape Agate is near you while you sleep it stimulates your crown chakra and provides vivid messages and dreams.  As a whimsical gemstone it holds a great deal of energy which is quickly tapped into, and can facilitate long, intense connections during meditation.  The gemstone offers you a unique perspective and encourages you to look within for answers to life and situations.  Grape Agate is also a wonderful gemstone for activating the inner goddess and working with goddess energies.
