While researching a totally different topic, I stumbled across the site of the Central Premonitions Registry.
The CPR are interested in hearing from people who believe that they have had a precognition or dream – even if you think that they are trivial and of no significance.
According to the site, your dreams and comments are confidential, so will never reveal your identity to others.
History of Central Premonitions Registries
There have been two previous attempts to run such institutes. One was the Central Premonitions Registry in the U.S.A., and the other was the British Premonitions Bureau in England.
How did it all start? On Oct. 21, 1966 there was the famous Aberfan disaster, when a coal mine collapsed in the Welsh village Aberfan and killed 128 school children. The British Psychiatrist Barker assumed that since this event caused such strong emotions and a storm in the media, it was very likely that some people had dreamt about it before. So he requested people through the Media to contact him about this. Of 76 answers that arrived, there were 24 that had sufficient corroboration, and these 24 case Barker ranked by order of strength of the evidence for Precognition. One of the best cases was that of a 47 year old woman from Plymouth that dreamt about an old school building in a valley, and then there was a Welsh coal miner, and then an avalanche of coal down a mountain. Near the bottom of the mountain was a little boy with a large stroke of hair that looked scared to death, and then she saw various rescue operations and had the feeling that this boy was saved. Near the boy stood in the dream one of the rescue workers, who was wearing a strange pointed hat. This Lady described her dream in Church on the Saturday, Oct. 20, 1966 (one day before the disaster), and there were 6 witnesses who later corroborated this. The next day, on Sunday at 8.30 in the morning (still before the disaster occurred on that day) she also told about it to her neighbor, who also confirmed the testimony. And that day in the evening, the British TV report on the disaster showed this small child talking to a reporter, and a rescue worker with exactly the same hat as reported in the dream. This research on the Abrefan disaster was published on the British Journal of the Society for Psychic Research (vol. 44), 1967.
