The chalom is one of the Tanakh's working channels of revelation. Yosef's whole story turns on dreams, his own and Pharaoh's (Genesis 37, 40-41). Daniel's career is built on them. Joel 3:1 promises that when the Ruach is poured out on all flesh, old men will dream dreams. HaShem takes the dream seriously as a way of speaking, and so does the Torah.

But Numbers 12:6 files the dream where it belongs: in the ordinary-prophet grade. "If there is a prophet among you, I make Myself known to him ba-mar'ah, in the vision; ba-chalom, in the dream, I speak with him." The dream is real speech and indirect speech at once. It arrives in symbols, it needs interpretation, and Genesis 40:8 says where interpretation belongs: "Do not interpretations belong to God?" Deuteronomy 13 adds the governing rule: a dream, however accurate, never outranks the Covenant. The dreamer who uses a fulfilled dream to pull you toward other gods has failed the test the dream itself was. Dreams are a grade of hearing, not a substitute for the face to face.
