There is an idea, if you shiver, that that means someone or something is walking over your eventual grave-site. The something is usually a goose and there is doubtless a connection between the idea of shivering and goose-bumps, the visible signs of cold or �shiveriness' on your skin.
In the same way, an itchy palm supposedly means money is coming your way, having 'burning ears' supposedly means someone somewhere is talking about you and there are many other similar beliefs.
All of these examples are superstitious hangovers from the days of witchcraft/angels etc, when people believed they were constantly being offered signs and warnings of distant or future events.
