In 1977, the paranormal was recorded and its effects on the Harper family are well known in circles were the paranormal is firmly believed. The term poltergeist refers to the movement of objects or people due to paranormal reasons. Majority of such cases are known to involve children who are about to enter puberty or teenagers. This has given rise to speculation that this age group either causes or attracts poltergeist activity. This type of paranormal activity differs from regular ghost activity in the sense that there are no cold spots and no specters and such. If there are any entities involved then they tend to be more than ghostly wisps but may take the semblance of physical objects and prove quite dangerous.
A popular and well-researched case of such activity took place in England in the 1970. Peggy Harper was a single parent who lived with her four children in a three-bedroom apartment in London. In August 1977, her 11-year-old daughter Janet and 10-year-old son reported bed shakings, raps on the wall, and voluntary furniture movement. Peggy was not willing to believe this until she herself witnessed a dresser drag itself about 18 inches away from its position. Peggy moved the dresser back and to her surprise the dresser again moved the same distance and despite her further attempts, did not return to its original position.
Alarmed by this, the Harper family approached their neighbors in their nightclothes and asked for help. Eventually the police was called in to investigate and during their inspection, one officer witnessed a chair move on its own and also heard the rapping on the wall. The officer later signed a statement detailing everything the witnessed. The clergy and other mediums were also brought in but nothing helped stop these events. The whole matter eventually reached the press and two journalists visited this residence. They spent some time there but nothing happened. It was only when they were leaving that some Lego bricks began moving of their own accord. They took photographs of this but when the film was developed there was nothing where the moving bricks should have been.
Finally a reporter from the Daily Mail suggested that the Harper family contact the Society for Psychical Research. The investigator from the SPR, Maurice Grosse, arrived at the Harper residence a week after these incidents were first observed. He observed, along with other reporters, the doors opening and closing, objects flying, and the rapping sound from the walls. What was truly frustrating that all attempts to record the audio or stills of the events taking place did not work. The tapes were blanked out or damaged and in some instances the metal inside the recording instruments was bent out of shape. Despite these difficulties, numerous photographs were taken of levitation incidents as well as moving objects.
The whole thing escalated to dangerous levels and Janet and Rose, the two girls, became the focus of direct attacks. During some attacks, Janet was heard speaking in a different voice and identified herself as Bill. The Harpers did not know it but Bill had lived and died in that same house.
There are too many impartial witnesses and documents to completely negate what happened with the Harper family in 1977.
