The thirteenth chapter was pretty terrifying, sure, but we wait until Chapter 45 to address the terror of the number itself. It does have quite a history of being somewhat taboo among some cultures, particularly Western ones. In Christian cosmology, Jesus's last supper consisted of thirteen individuals, one of which was to betray him, which may have started the Friday the 13th superstition among cultures deriving significance from Christian sources. Monks also had a hard time with thirteen full moons in a calendar year, so it was considered unlucky. The story of the Jersey Devil states that the devil was the thirteenth child of Mother Leeds, who cursed it as she was giving birth. The number even has an official phobia dedicated to it: triskaidekaphobia. What a mouthful.
Somehow, I doubt this chapter will have much to do with anything listed above, though.
