You've just laid down for the night when suddenly doors slam and the curtains shift. The lights begin to flicker and a white mist forms in front of you. You shut your eyes and keep muttering, "ghosts aren't real." But then you open your eyes and realize that "harmless" mist has shifted into the form of a man, staring intensely at you, as he floats above your bed. What causes ghostly experiences? Are ghosts real? Why do certain people report numerous ghostly encounters and others none? For centuries these questions have intrigued, puzzled, and bedeviled science, skeptics, and even believers. Based on cutting-edge research and new theories, The Ghost Studies provides insight into some of life's greatest mysteries.
