to me its an interesting concept that i don't really know what to make of or how to wrap my head around exactly.
so i'm curious what you guys have to say about it.
i'm not sure if jung meant it as something mystical or if its just a fancy name for coincidence, or what?

Synchronicity is the experience of two or more events that are apparently causally unrelated or unlikely to occur together by chance, yet are experienced as occurring together in a meaningful manner. The concept of synchronicity was first described in this terminology by Carl Gustav Jung, a Swiss psychologist, in the 1920s.[1]

The concept does not question, or compete with, the notion of causality. Instead it maintains that, just as events may be grouped by cause, they may also be grouped by meaning. A grouping of events by meaning need not have an explanation in terms of cause and effect.

This concept was inspired to him by a patient's case that was in situation of impasse in treatment. Her exaggerate rationalism (animus inflation) was holding her back from assimilating unconscious materials. One night, the patient dreamt a golden scarab - cetonia aurata. The next day, during the psychotherapy session, a real insect this time, hit against the Jung's cabinet window. Jung caught it and discovered surprisingly that it was a golden scarab; a very rare presence for that climate.

So, the idea is all about coincidence: in this case, between the scarab dreamt by the patient and its appearance in reality, in the psychotherapy cabinet.
