Nice one. I personally think that they are fed by the persons belief in any particular superstition. That is to say, should someone truly believe that breaking a mirror would bring about 7 years bad luck (for example) in their mind every bad thing that happens to them will be attributed to the mirror, while good things will be discounted. Personal beliefs play a huge role in a persons psychological make up. Myself, I'm not superstitious when it comes to mirrors and what have you, however, I will not leave the house with out a few crystals with me. I'm not sure if this falls under superstition or security blanket, regardless, they give me piece of mind. Hmmm come to think of it, maybe I am more neurotic than I thought I was.
