Psychologist Carl Jung was the first scientist to attempt to explain this amazing phenomenon. Jung treated many hysterics and distraught people in his psychiatric practice. He was especially fond of hearing about patient's dreams. Over a decade of administering therapy, he noted an uncanny relationship between the content of dreams, odd coincidental events and the successful restoration to mental health of his patients. This is the first of several expeditions into the world of pattern, chance, magic and significance.
Some people feel that coincidence is the guiding force in their lives.
To them, coincidence is a force which influences decisions and plans and has as much impact on their lives as others who may believe in Astrology. The definition of synchronicity, according to Carl Jung, is a meaningful coincidence, i.e. a coincidence that holds some personal significance for the observer. What that factor which appears to us as 'meaning' may be in itself, we have no possibility of knowing. It has also been suggested that the term synchronicity, for many, refers to a remarkable coincidence which would be assumed to have a very low probability of occurring, yet occurs just the same. In physics, we are taught that every single particle in the universe has a gravitational effect upon every other particle, no matter how far the particles are separated.
