The term synchronicity is coined by Jung to express a concept that belongs to him: the acausal connection of two or more psychic and physical phenomena.
Cetonia Aurata or the
This concept was inspired to him by a patient’s case that was in situation of impasse in treatment. 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.
But this coincidence is not senseless, a simple coincidence. By using the amplification method, Jung associates in connection with the scarab and comes to the concept of death and rebirth from the esoteric philosophy of antiquity, a process that, in a symbolic way, the patient should experience for a renewal and vitalization of her unilateral personality, the cause of the neurosis she was suffering from.
Thus, a significant coincidence of physical and psychological phenomena that are acausal connected.
