Term coined by Carl Jung for the phenomenon of an apparent pattern of coincidental events which, while lacking any causal relationship, bear a meaningful relationship to the observer.

Example: A hot air balloon makes an emergency landing in your yard just as you're imagining what it's like to ride one.
I can't believe there is not a single reasonably correct and straight-forward definition provided for "synchronicity" here.

1. Moving or operating at the same rate.

NOTE: Commonly used interchangeably with the term "Symmetric" in reference to describing Digital Subscriber Line (DSL) data connections in the communications industry.
"An Synchronous Digital Subscriber Line (SDSL) connection is far better than ADSL or Dialup."

A real life to dream relation. To have a connection or think something has happened before. Very similar to deja vu or to know something in a dream before it actually happens in real life.
Girl 1: I think I have synchronicity!
Girl 2: wait isn't that when you know what is going to happen in real life because it has happened to you in a dream!!!
Girl 1: BINGO
