In Thai culture, ghosts, known as phi, play a significant role in folklore and daily life. They are believed to be spirits of the deceased who have not found peace, often linked to unfinished business or strong emotions. Various types of phi exist, each with unique characteristics and stories, such as phi pop, a ghost that can possess the living. Thai people often perform rituals and make offerings to appease these spirits, especially during festivals like Songkran and Loy Krathong. These practices reflect a deep respect for the spiritual world and the belief that honoring phi can bring good fortune and protection to the living.
