사하인 is a term used in Korean culture to refer to a specific type of spirit or ghost. These spirits are often believed to be the souls of individuals who have died in tragic or untimely circumstances. In folklore, 사하인 are thought to wander the earth, seeking peace or resolution for their unfinished business. In traditional beliefs, 사하인 can be associated with various rituals and practices aimed at appeasing these spirits. People may perform ceremonies or offer food to honor the 사하인, hoping to bring comfort to the restless souls and prevent any misfortune that might arise from their presence.
