Galley Beggar
This is an old English ghost, often reported in the North of England and mentioned as far back as 1584, in Reginald Scot's The Discovery of Witchcraft. This fearsome ghost is described as being almost without flesh and bearing it's head under it's arm and emitting a deathly scream. The name is derived from the word 'Gallery', meaning to terrify. This ghost is likely to be encountered on country roads and deserted lanes.

Ghoul
From the common name for a ghost in Arabic. Nowadays commonly used throughout the World to define a nasty or viscous looking ghost. The ghoul is believed to gain sustenance from eating the flesh of corpses - hence ghoul is often used to describe ghost that haunt graveyards.

Graveyard Ghosts
According to folklore, the first person to be buried in a churchyard was believed to return as a ghost to guard the site against the Devil. This ghost was supposed to have special abilities. Because the task was so great, a black dog or more rarely a cat was buried before any human so it would become the guardian of the dead. Ghouls are also associated with graveyard hauntings.

Gremlin
These have only appeared in recent times and the word is believed to have originated during WW2 when pilots often reported strange goblin like creatures in the aircraft with them. Gremlins were immortalised by Steven Speilberg in his highly entertaining film of the same name and today hardly a piece of machinery can go wrong without somebody blaming 'A gremlin in the works'.

Grey Ladies
Said to originate in Tudor times when the dissolution of the monasteries resulted in a great number of monks and nuns being made homeless. Nuns at that time were frequently habited in grey. Many other investigators subscribe to the theory that grey ladies are similar to white ladies, whilst others claim the colour is related to the surrounding substance, wood, plaster, stone which may contribute to the ghosts appearance.

Ghost Hunter - A person who uses standards set by researchers to search for haunted areas, in probable locations
such as cemeteries, abandoned buildings, old churches, battle fields, old schools, etc.

Haunting - Paranormal experiences occurring over a period of time in a specific location. May include apparitions, sounds, smells, moving / disappearing objects, etc.

Halloween
Originating long before the advent of Christianity, The Feast of the Dead is perhaps a better name for the night. It was a time of great celebration for our ancient ancestors who would light great bonfires to try and summon and placate the dead. The Christian churches tried to mask the true meaning of the celebration by declaring it to be 'All Hallows Eve' the night before All Saints day. Modern witches still celebrate the night of 31st October by the holding of feasts and performance of rituals.

Haunted Chairs
There are many reported instances throughout England of owners who have a particular fondness for or may have died in an armchair. Returning as a ghost and being seen in that particular chair. The ghost of Lord Combermere was reportedly photographed in his favourite chair, whilst his body was being interred nearby. Chairs also feature in many legends, chairs that cause death or misfortune to the sitter and chairs that result in the pregnancy of the female sitter.

Intelligent Haunting - When spirits seem to live in a specific area, and act with free will, as well as show intelligence (i.e., not residual). Spirits don't necessarily haunt the place they die at, but could haunt the most comfortable place for them to stay (i.e., their old home).

Thought to be a talisman against bad magic, witches and evil spirits. Used by many cultures in the past. Saxon burials frequently contain iron talisman to protect the spirit of the deceased in his journey into the afterlife.

Mermaid Pools
Pools of doom, death pools or back water. These refer to many secluded ponds and lakes which are said to be haunted by a certain type of mischief making ghost. Many people report feelings of sadness and melancholy. Most of these pools also have legend of people being drowned and lost forever within their waters. The legend may extend back to ancient times when water dieties were worshipped in many cultures, a practise that often involved human sacrifice - the body being thrown into the water.

Orbs- This is the most common type of spirit energy to be captured on film. These will appear as solid or transparent "balls". They appear in many shapes and some colours, with white being the most common.

Ouija board
Consisting normally of 38 figured cards arranged in a circle. The letters of the alphabet and the number zero are nine are represented together with two further cards with the words yes and no upon them. Derived from the French and German words for 'yes' thus the board is correctly called the 'YesYes' board. It is alleged to act as a mediator between the worlds of the living and the dead. In use a glass or pointer is used to indicate the letters and words being spelled out by the spirits. The board also carries with it a fearsome reputation for demonic possession to those using it although in more enlightened modern times it is now believed to be a form of dowsing.

Paranormal Researcher - Someone who uses their own theories/ideas to test new research methods, protocols, and equipment. A true researcher is not biased to an old idea, but works to disprove or prove further the old idea, to expand the knowledge of the community. Typically, a researcher does not work to prove a paranormal occurrence as genuine, but to disprove the occurrence legitimately. Only when all possible false-positive contaminants have been ruled out can something be defined as a true anomaly.

Paranormal Investigation - The act of going to a supposedly haunted location, gathering data such as photos, audio recordings, video, electromagnetic field monitoring, etc., and summarizing your data in reports (which does not exclude psychic impressions, but are subjective data until proven otherwise). A true investigator can't draw conclusions from one investigation, it may take several investigations to decide on a site's activity.

Raps - Unexplained knocking sounds associated with poltergeist activity.

Research Site - A true research site is one where a controlled environment can be established, and then visited frequented (normally on a regular basis, weekly, biweekly, etc.) to test new theories and research ideas. To a researcher, the benefits of a long-term research site is being able to find norms for that location, therefore deviations from that norm can be found recorded as data. This isn't possible on an investigation, where one may only visit a site only a few times.

Residual Haunting - Not technically referred to as a haunting, but more of an energy imprint. When a spirit is seen doing the same thing at specific intervals constantly. Perhaps the spirit is trapped repeating a specific moment in life, or perhaps it is just a flash from the past during a traumatic moment in someone's life.
