A ghost is considered the soul of a dead individual which refuses to leave our world and move on. Ghosts usually have something in this world to hold on to, for instance, the houses where they were living as human beings, or the places they loved visiting when they were alive. The people they were in love with can also force ghosts to linger on in this world. While ghosts haunt certain places, they are usually harmless. One needs the services of religious people who are capable of performing religious ceremonies in order to cleanse places that are haunted, and make ghosts leave our world.

Poltergeists are aggressive and very difficult to control; they are capable of harming people and make their presence felt by moving objects. They can further use these objects to hurt people very easily. In case you find yourself in a place which is occupied by a poltergeist, it is recommended that you leave the area and never visit it again if you value your life and health. Humans are rarely allowed to live in peace in areas that are occupied by this entity.
