Where do superstitions come from?

[Oerets]

Fear of the unknown or the inability to understand the happenings in front of them. Causes the imagination to conjure up an explanation. Understandable considering that we are always looking for answers to the unexplainable.

But then there are superstitions based on facts. Like the one about three on a match being bad luck. But one if not worried about a sniper and not in a trench then no worries.
