My father's uncle went to the local club one night and told everybody he saw his wife by his bed last night [she had died some years prior], I forget whether he said he spoke with her, anyway, everybody just accepted it, not knowing what to think, he wasn't a wishy-washy person or taken to superstition, quite the contrary - low and behold he died a night or two later in his sleep! His story about his wife was then discussed a little more rigorously!
