Friday the 13th continues to stir a primal sense of dread, even in this day and age. This date has been linked to everything from biblical betrayals to natural disasters and psychological terror. While some treat it as an amusing superstition, others genuinely avoid flights, major purchases, or even getting out of bed on this fated date.
Hollywood famously immortalized Friday the 13th in slasher films, but real-world disasters and curious coincidences only add fuel to the superstitious fire.
