Extreme Ghost Stories is a British supernatural documentary television series produced by ITV Granada, consisting of four one hour episodes.
In 2005, ITV Granada appealed for those whose lives had been affected by ghostly experiences to contact the station regarding production of a paranormal series.
The series features drama reconstructions of ghostly encounters of some well-known haunted locations as well as individual cases not known to paranormal enthusiasts.
A recurring supernatural entity in the series is the black mass, a dark form with a vaguely humanoid stance, which witnesses feel represents evil.
