Belief in demon possession exists in many religions around the world, including Christianity, Islam, Judaism, Hinduism, and various traditional spiritual practices. In fact, the Catholic Church still officially performs exorcisms — a ritual intended to cast out demons — and has trained priests specifically for this role. While some view possession as a spiritual or supernatural event, others interpret it as a reflection of mental health issues. The topic continues to be a mix of faith, tradition, and controversy in both religious and scientific communities.
