The experience of illness, disease, and suffering is one of the great universals of human existence. Throughout history, people have relied on dreams to help ease their sufferings and cure their ills. From a spiritual perspective, dreams have the power to heal illness because they renew and revitalize people's relationship to God, to the gods, to the forces of the spiritual world. Frequently, the very experience of this renewed relationship is enough to relieve an ill person's sufferings.
