Cultural background
The concept of a vengeful ghost seeking retribution for harm that it endured as a living person goes back to ancient times and is part of many cultures. According to such legends and beliefs, they roam the world of the living as restless spirits, seeking to have their grievances redressed, and may not be satisfied until they have succeeded in punishing either their murderers or their tormentors.
