Sensing the Unknown [PDF ebook] 

In 1912, Mrs. Marshall watched passengers board the famous ship Titanic in England. As she watched the ship leave port, a vision flashed in her mind: "That ship is going to sink." Four days later, the ship struck an iceberg and sank in the ocean. Her psychic vision came true. Is such a thing possible? Can a person truly predict an event before it happens? This book examines psychic paranormal powers, such as precognition and clairvoyance, and allows readers to determine if they believe in "seeing" the future, or if it’s all a huge hoax.
