The Windmill The Windmill was once said to be haunted by a poltergeist.
Still, research has revealed that poltergeist cases are almost always caused by a living human.
Instead, a poltergeist is believed to be a form of psychokinetic energy manifested by a living person who is unaware of what they are doing.
It has been an active scene of poltergeist activity since the 1980s.
In 1907, in northern Ireland, a farmer's house was troubled with flying stones (see Poltergeist).
