Physics: Synchronicity

Synchronicity and coincidence. What's the difference?

Synchronicity: the simultaneous occurrence of events which appear significantly related but have no discernible causal connection

Coincidence: a remarkable concurrence of events or circumstances without apparent causal connection

The above definitions sound pretty much the same. "Remarkable concurrence" and "Simultaneous occurrence of events which appear significantly related" are two different wordings of the same thing.

Further research indicates that Synchronicity applies to phenomena that which includes parapsychology: premonition, telepathy, dreams, astrology, etc. This term is also seen in Jungian psychotherapy- situations where the psychotherapists get information about their patients and vice versa, information that was not told to each other or found public yet just "known" via, presumably, telepathic, intuitive, or these sort of ways.

I found myself curious about the validity of "Synchronicity" being that there is a lot of controversy surrounding its truth. Some say its pseudoscience while others, like Carl Jung, claim it is the only way to explain an experience that which makes little sense to person in that situation. It can therefore be considered a "bridge with one foundation derived into the objectivity of hard science and the other into the subjectivity of personal values."

Stumbling upon other interesting studies, it was found that high levels of dopamine affect the propensity to find meaning, patterns, and significance where there is none, and that this propensity is relate to a tendency to believe in the paranormal. This got me wondering about the connection between those that practice meditation or any other "spiritual art," and if it is the high levels of dopamine derived from these practices that is driving the synchronicity experiences- it seems like these experiences are shared mostly among those that have these sort of lifestyles.

So... is it made of in someone's head due to "high levels of dopamine" or the ability to achieve a more or less higher level of consciousness when practicing strong self-aware and spiritual practices?
