That's how you do a season finale!
I personally like this explanation in so much as, I do believe in God and believe he is the Almighty but I do not believe in organized religion as it has become more business than true religion, and, I believe that when the books of the Bible were chosen, by men, and re-written by a King, that women, one specifically, Mary Magdalene, were vilified to suit the times. (but that is a whole different blog post, for a later date)
Anathema
Still other sources speculate that the number 13 may have been purposely vilified by the founders of patriarchal religions in the early days of western civilization because it represented femininity. Thirteen is said to have been revered in prehistoric goddess-worshiping cultures because it corresponded to the number of lunar (menstrual) cycles in a year (13 x 28 = 364 days). The "Earth Mother of Laussel," for example — a 27,000-year-old carving found near the Lascaux caves in France often cited as an icon of matriarchal spirituality — depicts a female figure holding a crescent-shaped horn bearing 13 notches. As the solar calendar triumphed over the lunar with the rise of male-dominated civilization, so did the "perfect" number 12 over the "imperfect" number 13, thereafter considered anathema.
I have heard of people being so scared of Friday the 13th they won't even leave their homes as stated in this article by John Roach for National Geographic.
Though written in 2004 I don't think much has changed as far as this superstition is concerned.

As for me, I'm taking a 6 hour road trip, on a wet rainy day, with clouds so thick it looks like night outside.
