Hang on a minute. There are many things which seem to be coincidences and are statistically to be expected, but what hippie told us what beyond that.
Two people have the same "feeling" at the same time to go somewhere to meet the other, who they haven't seen for 20 years? Both act upon that feeling? (IMO, that is one of the most amazing things about that story, that neither of them shoved the thought aside, and that they were even moved to write to each other after the event). THAT is not statistically likely AT ALL.
I think that one day scientists will admit what is plain for all to see; there is some form of communication between minds and we don't quite understand it yet. This communication can travel across the globe in seconds without any equipment apart from your brain.
