Have you made a note of things that you've dreamed about which did NOT later become part of a memorable coincidence? I'd be interested to know how many of these there were ~ things, people, thoughts which had no reason to imprint themselves on your memory ~ compared to the number of coincidences that DID imprint themselves on your memory... and thus became the kind of anecdotal evidence you offered here.
I generally don't dream about people from my past though, unless they pop up shortly after the dream. That's what is unnerving.
