Death by Red Ink

A common superstition that started ages ago and is still feared to this day is the myth that writing a living person's name in red ink will result in extremely bad luck, or worse, death. Originating during the Qin dynasty in China and later influencing Korea, the myth took root for several reasons. The primary one was that during these times, only the King was allowed to wear red and would punish anyone else who dared to. The color red is also the same color as blood, which is often associated with pain or death. In Korea, red ink was historically reserved for the names of the deceased in family registers and on funeral banners. This Halloween, it is better to be safe than sorry, so avoid picking up any red stationery when writing a friend's name.

Friendly Whistling

Walking home late at night might get boring, but do not dare start to whistle! The thought behind this Korean urban legend is that whistling at night will summon spirits, demons, and even snakes. Often viewed as an action of contentment, whistling is thought to be the favorite tune of these creepy creatures. Good or bad, one might not know, but what are the chances that you will meet Casper the Friendly Ghost while walking home at night? The superstition was also used to quiet noisy children after dark, but the chilling reputation has stuck around for generations.

Blinded by Beauty

Used to symbolize a long-lasting marriage in traditional Korean weddings, butterflies are often seen as wonderful insects with delicate wings. However, do not get blindsided by their beauty! This superstition goes that if you touch a butterfly and then touch your eyes, you will go blind. Why would someone do such a thing? Who knows, but just be wary of what you go around touching this Halloween, especially anything fluttering around in your garden.

Between Death and Life

Having started back during the Mongol invasion of Korea in 1270, this superstition will have you thinking twice before walking into any home. It was during these years when those who had died in the comfort of their home would remain there for some time. Afterwards, they would be taken out of their house in a coffin. It is believed that once the coffin passes through the front door, the boundary between the living and the dead has also been crossed. Thus, stepping on the threshold afterward is thought to bring bad luck to anyone who crosses the household after.

Lucky Number 4

This superstition originated from China, where the word for "four" (sì) closely sounds like the word for "death" (sǐ), and supposedly brings bad luck. Because the Korean number system closely resembles that of China's, the same beliefs come into play. To see how seriously they take this superstition, walk into any tall building in Korea and take the elevator to the fourth floor. Cannot find it? That is because the number has either been replaced with the letter F to signify the same thing, or removed completely. Hospitals, hotels, and apartment buildings often skip the 4th floor entirely to keep bad luck at bay.
