Octophobia (from Greek okto, "eight") is fear of the number eight, a branch of numerophobia. The fear is often due to the looping figure of the number itself, as well as superstition. The fear of 8 is connected to the fear of 26 as the sum of digits in 26 is 8. Due to this numerological property, the number could bring about bad luck, hardship, and destruction.
An octophobic person may believe that number 8 may hold danger in things. For some, the figure eight pattern spirals into a never ending curve that can make them dizzy. Since eight is perpendicular in figure to the infinity sign, octophobia may lead to or developed from apeirophobia.
Some living in a home that has number 8 on its address may worry that it gets destroyed some day. Others would not wed during the eighth day of the month nor the eighth month of the year (August). If the person glances at the number, he/she may get stunned by it, but if it gazes at that number, he/she may panic while giving them a sense of inescapability.
Surprisingly, most people believe even though it doesn't have a cure for it, the fear is adjustable. But the phobia can be treated; psychotherapy is the most beneficial.
It is mainly suffered in Bulgaria and India because in Bulgaria, a phone number called 0888-888-888 was a cursed phone number because all those who have owned this phone number had died. The first one who owned this number, Vladimir Grashnov, died of cancer in 2001, although some believed a rival poisoned him to death. The second one who owned this number, Konstantin Dimitrov, was gunned down by rival Russian mafias in the Netherlands in 2003. And the third and last one who owned this number, Konstantin Dishliev, died in Bulgaria after being shot outside of a restaurant in 2005. Then this phone number was suspended ever since. It is also unlucky in India because it's the number of Sani, which is relation breaker, peace breaker and lethargic kind of personality.
