synchronicity
This term describes a meaningful coincidence where two or more events occur together without a direct cause-and-effect relationship. It carries a mystical or psychological connotation, suggesting that the universe or the subconscious mind is communicating a pattern or a sign to the observer. Because it refers to a specific conceptual phenomenon, it is treated as an uncountable noun. It does not refer to a countable number of coincidences, but rather to the quality or state of being synchronous in a meaningful way.
Meanings
The simultaneous occurrence of events which appear significantly related but have no discernible causal connection.
"The sudden phone call from an old friend just as I was thinking about him felt like a moment of pure synchronicity."
