When surprising coincidences occur, it seems we are connected to the world around us in a mysterious way. For example, you are thinking about a song you haven’t heard in years, and as you have this thought the song starts playing on the radio. In this case, it seems your mind is connected to the world around you—the coincidence occurs between a mental state and a physical state.
Coincidence also appears between the psyche of two individuals. For example, you and your friend simultaneously buy identical shirts without knowing it.
“Synchronicity phenomena are characterized by a significant coincidence which appears between a (subjective) mental state and an event occurring in the (objective) external world,” explained Francois Martin, Ph.D., of the Laboratory of Theoretical Physics at the University of Paris, and Federico Carminati, Ph.D., Physicist at the European Organization for Nuclear Research (CERN), in a paper titled “Synchronicity, Quantum Information and the Psyche,” published in the Journal of Cosmology in 2009.
