The Divine Scepter
Ghosts most often appear because of three primary reasons:
1. In life, the ghost was a notorious and powerful soul.
2. A mortal being was not able to accomplish a major goal.
3. Something has disrupted the dead, causing the ghost to appear.
Sometimes ghosts are conscious of their state, but occasionally they unaware they are undead. In some cases, the ghosts repeat the last day of their life each day.
