The British Premonitions Bureau was formed in 1966 by psychiatrist John Barker after the Aberfan mining disaster in which 144 people, including 116 children, died when 500,000 tons of debris smashed through the Welsh town and buried the primary school. Reports of precognitive dreams foretelling of the catastrophe prompted Barker to form the bureau in the hope of predicting and avoiding future tragedies. In the 18 months the Premonitions Bureau was open, nearly 1000 reports of premonitions were collected, and while a few seemed to foretell disasters, over 90 percent failed to predict future events and none prevented any disasters.
