Hallucinations in Religion:

Hearing voices occurs in every culture and has often been accorded great importance—the gods of Greek myth often spoke to mortals, and the gods of the great monotheistic traditions, too. Voices have been significant in this regard, perhaps more so than visions, for voices, language, can convey an explicit message or command as images alone cannot.
