The devastating problem with “synchronicity” is post hoc ergo propter hoc. If I am in the wood and I expect to see a doe, a female deer, and I see that deer, how many other times did I have such an expectation and see nothing? You remember it when you see something. When you think it and nothing comes, you totally forget it (what you thank/thought). All the non-meaningfulness is swept under the rug, so to speak. Self-deception runs amok in our consciousnesses. We find meaning everywhere. We find meaning in being Nazis, in being pedophiles. Finding meaning does not suffice as justification.
