鬼魂, or "ghosts," are often described as the spirits of deceased individuals who have not yet moved on to the afterlife. In many cultures, they are believed to linger in the physical world due to unfinished business, strong emotions, or a desire to communicate with the living. These entities are commonly depicted in folklore and popular media, often associated with haunting locations or appearing to loved ones. The concept of 鬼魂 varies widely across cultures, with different beliefs about their nature, appearance, and the ways they interact with the living, such as in 日本 or 西方文化.
