Hexekontadyophobia (from Greek hexḗkonta, "sixty", and dyo, "two") is the fear of number 62. The only documented case of a person who feared number 62 was psychologist Sigmund Freud, who lived from 1856 till 1939. Due to this irrational fear, he would not book a room in any hotel with more than 62 rooms in case he was allotted that particular room.
