Synchronicity
Synchronicity is the concept formulated by Carl Jung in Synchronicity: An Acausal Connecting Principle (1952). Describes "meaningful coincidences" — events without causal connection that share psychological meaning. Theoretical foundation that gives intellectual legitimacy to oracular practices.
Examples
You think of a friend and they call. You tarot consult and the card matches what you were feeling. Jung gave the famous example of the "golden scarab" in the office of a patient — beetle entered exactly when she described an Egyptian scarab in a dream.
