To the rabbis, dreams were a serious theological challenge. While in the Hebrew Bible dreams could be prophetic and therefore a source of authority, rabbinic authority was based on textual interpretation rather than direct revelation. This article examines one rabbinic strategy for responding to this challenge: the Talmudic dream ritual of Berakhot 55b. Through this ritual the rabbis place the dreamer in the position of a supplicant. Dreaming becomes like an illness or curse rather than a revelation. Instead of telling the dream, the dreamer prays for its healing. This article argues that this ritual itself is a form of interpretation, both of the dreamer’s dream and of the biblical texts about dreaming, in which the biblical idea of revelation through dreams is retained but the dream itself is stripped of any specific prophetic meaning. Through the performative speech of this ritual the dreamer places the dangerous dream under the power of rabbinic authority.
