I agree with you on Law of Attraction, especially vision board bull shit and how people get accused of putting out bad energy to explain why bad things happen to good people. Anyway, as for synchronicity and Carl Jung, from my personal experiences, I am big believer, and certainly do not begrudge your materialist stance as you do not preach against mine (I only have issue with those that insist on trolling us to preach their perceived superiority of their position--one told me anyone who believes in god is mentally ill). To each our own. Your friends who point you to Jung would like this piece of mine about a pub I started called ChannSpirations and Coincidences https://medium.com/illumination/what-is-channspirations-97516b44185a
