As long as we are talking about weird stuff, what are your views on ghosts? Some of the most otherwise hard-headed, pragmatic individuals I have known claim to have seen ghosts and experienced related phenomena. In addition, their existence has been just about universally accepted in all human cultures around the globe. I have never seen a ghost, but I will listen respectfully and open-mindedly to anyone who claims he or she has--far moreso than if an individual claims to have encountered Bigfoot or UFOs and ETs, for example. Your thoughts?
