People report knowing things they had not previously had the opportunity to learn.
I have some recall too of a life as a monk in Beaulieu Abbey (1203-1538) in Hampshire, England. My husband and I went to its site which has some of the original buildings. I was able to describe the entire original layout of the abbey church, now only an open space. My description was consistent with historical documentation, although I had never been there or read of the abbey. (Certified by college professor after visit with her husband.)
In a university staff room filled with sceptics, several number related that they have experienced remarkable foreknowledge, for instance of the detailed layout of a town in a country they had never visited. One gave precise, very detailed directions for his wife (who was quite shocked as later was he) to an old bank in a Scottish town. They had never been in the country and had pulled up at a B & B outside the town rather than face peak hour traffic and drive in. Another recalled his death in an overturned canoe during a storm at sea. He believes that death happened when he was Polynesian and on a fishing trip. His feeling of comfort in Polynesia and his love of the Polynesian ways is quite extraordinary (well known to university colleagues).
