Demonic possession is a belief that an evil spirit or demon takes control of a person's body and mind. This phenomenon is often characterized by unusual behavior, changes in personality, and sometimes physical symptoms. Many cultures and religions have their own interpretations of possession, often linking it to spiritual or moral conflicts. In various religious texts, such as the Bible and Quran, there are accounts of individuals being possessed and later exorcised, or freed, by spiritual leaders. Treatments for possession can include rituals, prayers, or other spiritual practices aimed at restoring the person's well-being and driving out the malevolent entity.
