A ghost is a soul or spirit of an individual who used to be a flesh and blood human (or animal) and passed into the afterlife. Some people, often those close to the deceased person, report’seeing’ this ghost after their death. Often, they feel the person is near them or hear their voice and can even smell their perfume. Seeing and experiencing a ghost is a very real experience for those who have it.
Ghosts, like the poltergeist or ectoplasm, can be good or bad. It is thought that a ghost is simply replaying the energy of the soul or life it once was. But the energy can be distorted or manipulated to create a more negative outcome.
The appearance of a ghost can be anything from a translucent, white mist to the old standby of a skeletal form and scars or cuts on the neck showing how the person died. The ghost may manifest at the site or building where they died, or in a specific object. Generally, ghosts have unfinished business and want to be at peace.
It is important for the writer to develop the ghost character, a little like creating any other main character in a story. This can help to add depth, authenticity and contribute to the overall theme of the story. Having an interesting backstory, motivations and powers can help to make the ghost a more believable entity in the story. In addition, ghosts can be aided by other characters in the story called foils who can reinforce aspects of their personality.
