In Thai culture, ghosts, known as phi, are believed to be spirits of the deceased who have not found peace. They are often associated with specific locations, such as homes or forests, and can be categorized into various types, each with unique characteristics and stories. Some phi are thought to be benevolent, while others may be vengeful or mischievous. Thai folklore includes famous ghost stories, such as that of Mae Nak, a woman who died during childbirth but returned to haunt her husband. These tales are often shared during festivals and gatherings, reflecting the deep-rooted beliefs in the supernatural within Thai society.
