"Ancient traditions have long associated holy wells and springs as very special places of the Goddess or anima mundi: symbolic of the Great Mother and associated with birth, the feminine principle, the universal womb, the prima materia, the waters of fertility and refreshment and the fountain of life. The dreaming sites, as they are called, have also been associated with visions, healing, and other paranormal experiences. In ancient Greece, for example, there were more than three-hundred medical centers placed at water sources, where patients experienced healing."
