An examination of dreams and visions that appear in the Hebrew Bible. Since Freud, the rational modern approach to human dreams has typically involved inquiry into past emotional states. In contrast, the ancients, unfamiliar with the intricate byways of the human soul revealed by modern psychology, saw dreams as channels of communication between human beings and external sources. Shaul Bar examines dozens of the dreams and visions in the Hebrew Bible, categorizes them as prophetic, sumbolic, or incubation dreams, compares and contrasts them with corresponding phenomena in the literature of neighboring cultures, and analyzes their functions in the biblical corpus. A Letter That Has Not Been Read will intrigue students and scholars of the Hebrew Bible and anyone interested in the study of dreams.
