Ghost
The disembodied Spirit of a deceased person or animal. Ghosts are mainly experienced in very old buildings, the scene of an unexpected death, Graveyards or other locations associated with the dead in some way. In most cases, Ghost reports include unexplained noises, cold spots, rappings, footsteps and other phenomena that cannot be otherwise explained. Some think that a Ghost purposely choses to remain associated with a location after death, perhaps because that in life, that location had had some significane to that person. Some also believe that Ghosts persist because they are trapped between this world and the afterlife, or don't actually know that they are dead. Spiritualist Mediums are often consulted to try and communicate with a Ghost at a Haunted location.
Globster
Name given to any beached animal carcass that cannot be readily identified. Such remains are often classed as Sea Monsters due to the fact that they cannot immediately be identified as any known species of animal.
Gray
The most commonly reported form of Alien entity. Grays are characterised by being small, thin beings, with large eyes and greyish/brown coloured skin. They are hairless, and are reported on some occasions as wearing metallic skin-tight "space suits". There is no scientific evidence to support the existence of Grays, however that doesn't alter the fact that they are the most commonly accepted form of alien creature.
