A knock or bang is a sharp rapping sound emanating from a location within a room. These can be loud or soft and sound as if the origin is far away or close to the listener. Usually no reasonable explanation for the cause can be determined nor can the sound be duplicated using objects in the location. If a knocks are heard in response to a series of questions, this would be considered Audio Interaction.
Element
Ho: Haunted Object
An object which is the focus of paranormal activity, usually for which the removal of the object from the location causes the activity to cease. Example would be a haunted or spirited doll, the most famous cases being Annabelle and Robert the doll.
Hn: Hypnagogic Phenomenon
This phenomenon involves paranormal events which seem to occur when a person is just falling asleep or just waking up. This relates to strange sights, sounds, visions and other experiences during these transitions. To be considered paranormal, these events must coincide with additional evidence that the person is not merely dreaming.
Gm: Glitch In The Matrix
A pop culture term for the appearance of strange events that may reveal that reality may actually be a type of simulation. This concept was once proposed by Phillip K. Dick and was subsequently explored in the movie The Matrix, then written about in Children Of The Matrix by David Icke. Scientists believe there is evidence to support such a theory. Paranormal activity can be attributed to moments when the simulation breaks down briefly. May also be tied to the Mandela Effect, Divergent Reality and a variety of other strange events. This is considered to be a super pattern as it can contain other elements.
Ge: Geographic Anomaly
Localized geographic areas which coincide with heightened levels of paranormal activity. Examples include lay lines, energy vortexes, temporal magnetic anomalies, and areas in which mysterious disappearances have occurred.
