Ghosts are the spirits of dead people who still have some impotant news to finish in their life.
I Don't Want To Go To The Afterlife!Edit
Ghosts usually go back to the real life so they can carry on buissness, or they don't like the afterlife. But sometimes ghosts just wanna come back to do some scaring.
Ghosts are very scary to us humans, but they don't really mean any harm. Sightings of ghosts have gone on past thousands of years. The Egyptains believed that ghosts come from people kicked out of Heaven. Who knows what they could be!?
