Everyone has at least heard about the infamous Friday the 13th at least once in their lifetime. The number 13 comes with a lot of negative stigma or fear as many people are superstitious about the unlucky number. People are so scared that psychologists have actually come up with a word for the fear of Friday the 13th: paraskavedekatriaphobia. I thought it was a myth but recently as I paid close attention to my surroundings I found out that the hospital that I work at does not have room number 13. Furthermore, the place where I lived before, does not have building number 13. Are you starting to think that wait this is weird?
