Gerald of Wales, the famous clergyman and chronicler, wrote in 1191 of a house in Pembrokeshire that was filled with poltergeist activity. Here, the unseen spirit was said to have thrown handfuls of dirt, as well as tearing clothing and breaking objects in the house. Most frightening to those who experienced it, though, was the fact that this spirit was also said to vocalize all of the secrets of the people in the room.
