Can you give a few examples?
The nature of the events and the timing. Again, the claimed sequence of events for Teapots Happen was:
1) He had a mystical experience, which had absolutely nothing to do with teapots.
2) One week later, he felt compelled to buy a particular teapot.
3) One week after buying the teapot, he decided to explore the crawl space beneath the house he had lived in for eight years, and found the same style teapot buried there.
Extraordinarily so. Such as:
In his book Synchronicity (1952), Jung tells the following story as an example of a synchronistic event: "A young woman I was treating had, at a critical moment, a dream in which she was given a golden scarab. While she was telling me this dream, I sat with my back to the closed window. Suddenly I heard a noise behind me, like a gentle tapping. I turned round and saw a flying insect knocking against the window-pane from the outside. I opened the window and caught the creature in the air as it flew in. It was the nearest analogy to a golden scarab one finds in our latitudes, a scarabaeid beetle, the common rose-chafer (Cetonia aurata), which, contrary to its usual habits had evidently felt the urge to get into a dark room at this particular moment. I must admit that nothing like it ever happened to me before or since."
