The Ganzfeld Experiment is a parapsychological experiment which consists of two participants in separate rooms trying to communicate with each other using thought transference or telepathy. Telepathy is the transmission of information from one person to another without using any of our known senses or physical interaction. This experiment demonstrates that Telepathy is a real phenomenon, that information can be both sent and received using psychic methods.
Person A is deprived of sensory input and is bathed in a red light whilst person B views images on a TV screen and attempts to relay them to the next room. Person A vocalizes any words or feelings felt during the telepathic transmission which are recorded on tape or whatever. These telepathic thoughts and feelings are then compared with the original images send from Person A.
The results are astonishingly accurate. Time and time again the Ganzfeld experiments have yielded results that deviate from randomness to a significant degree. But this is nothing new is it? We know that Rhine and Zener demonstrated scientifically that Telepathy is a real phenomenon, or that Stamford Research Institute showed us that Remote Viewing and clairvoyance are real too.
Over the course of thousands of experiments, by the standards applied to any other science, ESP has been proven to exist.
