[Carl Jung and the J.B. Rhine Letter and Synchronicity]

(The link below is quite informative.)

According to the Jungian view, the collective unconscious is not at all an expression of
personal wishes and goals, but is a neutral entity, psychic in nature, that exists in an
absolutely transpersonal way.

Ascribing the arrangement of synchronistic events to the observer’s unconscious would thus be nothing other than a regression to primitive-magical thinking, in accordance with which it was earlier supposed that, for example, an eclipse could be “caused” by the malevolence of a sorcerer.

Jung even explicitly warned against taking the archetypes (of the collective unconscious) or psi-powers to be the causal agency of synchronistic events. ~Marie Louise von Franz, Psyche and Matter,(p. 231).
