Halloween Origami: Ghost
The belief in manifestations of the spirits of the dead is widespread, dating back to animism or ancestor worship in pre-literate cultures. It is not known for sure whether ghosts exist or not. Many believe they do exist from claims of sightings and evidence collected from technology designed for "ghost hunting". Although many believe they are fiction, that all ghost sightings are a result of overactive imaginations, pictures of ghosts are faked, and the evidence is a result from normal household activities, such as a furnace creating a electro-magnetic field which is believed to be a common sign of a ghost.
