I have experienced in my own life the peculiar tendency of some topics soliciting certain synchronicitous events more than others. The subject of the paranormal is one of them.

Here is an article by that renegade of paranormalist research Nick Redfern about some disturbing "coincidences" when exploring the topic of Men in Black for his books. The coincidences are reported even for those who just read his books. These seem more than can be chalked up to confirmation bias:
