"유령" is the Korean word for "ghost." In many cultures, including Korean folklore, ghosts are often seen as the spirits of deceased individuals who have not yet found peace. They are typically depicted as ethereal beings that can appear in various forms, sometimes resembling their living selves. In Korean traditions, there are various beliefs about how to interact with or appease these spirits. Some people perform rituals or ceremonies to honor their ancestors, hoping to ensure that their spirits remain calm and do not disturb the living. This practice reflects the importance of family and respect for the past in Korean culture.
