This book gathers a hundred of unusual events that have taken place in Spain and have been personally investigated by the author during the last decade. In all cases, the protagonists are those who describe their experiences, such as encounters with dead relatives and the messages they convey, terrifying reakles of diabolic dolls, apparitions of ghostly monks on Spanish roads, encounters with entities that seem to have emerged from other dimensions or impossible coincidences, among many other supernatural events. The research work carried out by Marcelino Requejo includes photographs, drawings and illustrations.
