Parapsychology is a science that has been considered unknown and vague for many centuries due to the absence of the methods that can prove its various phenomena scientifically. During the last decades parapsychology has become one of the most argumentative sciences and its phenomena are being studied intensively by many researchers. In this book Ajwad (the author of The Unknown about the Human Aura) writes about this science in a scientific and interesting way that is suitable for both laymen and researchers in this field of study. This book explains the major parapsychological phenomena like clairvoyance, psychokinesis, telepathy and out of body experience. In this book you can also read about one of the most fundamental link between the human body as a biologic system and the limbic system of the human brain. A chapter about some terms that are used in Parapsychology is included.
