I have a new essay at aboutSETI.com:
Many ufologists committed to the Extraterrestrial Hypothesis (ETH) exclude the Hopkinsville incident from their files because, at least in retrospect, it seems so implausible; attacking an isolated farmhouse hardly seems like the behavior expected of "real" extraterrestrials. Interestingly, journalists noted that purported psychic Edgar Cayce had grown up just south of Hopkinsville. Some Forteans wondered, not completely without justification, if there might be some sort of connection.
Do you know of other cases of seeming paranormal synchronicity?
