Interconnectedness of the universe

Carl jung identified synchronicity as the coincidencees that happen with no cause and effect but its significant. I used to have persecutory delusion during class because of the ideology and when professorstalk about something, meaningful coincidence happens. And when i discovered synchronicity my perception changed . I want to know how synchronicity is interconnected to the universe and how does the universe (the external world) affects our inner world (thoughts and feelings) thank you
