A dream-interpreter of the Talmudic tradition who understood, with perfect clarity, that he was never reading dreams at all — and charged accordingly.
The Talmud records that Bar Hadya gave favourable readings to those who paid him and ruinous ones to those who did not. Both kinds came true. The dreams chapter treats this not as fraud in the ordinary sense but as a confession: contradictory readings can all come true only when there is no real thing behind them to contradict — only when the meaning is manufactured by the interpretation, not discovered in the dream.
Bar Hadya is the chapter’s most honest villain because he demonstrates the create-pole from the inside. The dream, in the Talmudic formulation, is like a letter unread until someone interprets it; the interpretation does not discover the meaning, it makes it. Bar Hadya simply noticed the meaning ran in one direction and monetised it.
The Witness names him the ancestor of the monthly-subscription oracle: he runs today on a chat-window, and his readings still come true for the rabbi’s reason — because the reader is the one making them so. The mechanism is the same closed loop described in the divination chapter; only the interpreter’s robe is new.
