A Jung woman I was treating had, at a critical moment, a dream in which she was given a golden scarab. While she was telling me this dream I sat with my back to the closed window. Suddenly I heard a noise behind me, like a gentle tapping.
Jung’s first-person clinical account of the scarab synchronicity establishes the event as the canonical empirical demonstration of acausal meaningful coincidence.
