Synchronicity refers to a meaningful coincidence, an event or pattern that feels too significant to be random, even though there's no obvious cause-and-effect connection between the two things involved. The term was popularized by psychologist Carl Jung, though it's since become a common concept in spiritual and psychic contexts as well.

People often point to synchronicity when a specific number, symbol, or person keeps appearing at meaningful moments, interpreting the repetition as a sign worth paying attention to rather than dismissing it as coincidence.
