Most of us will have experienced a TEE, an experience of time slowing down in an extreme situation, and yet it is a phenomenon that has never been fully explored or explained - until now. Psychologist Dr. Steve Taylor has spent several years analysing “time expansion experiences” (or TEEs), after collecting hundreds of reports. He has also found many examples of "time cessation experiences" (or TCEs), in which time appears to disappear altogether. In this book he shares the fascinating psychology and shared features behind all of these case studies, coming to an incredible conclusion: TEEs are a real altered state of consciousness, rather than a trick of recollection. Not only this, but TEEs and TCEs are almost always positive, with a sense of calm well-being, clarity and heightened awareness. In this ground-breaking book, discover profound implications: What do unusual states of consciousness such as mystical experiences, psychedelic experiences, and near-death experiences tell us about time and consciousness? What can the countless reports of “life review” - when people view a whole lifetime of events and experiences within a few seconds - tell about the past, present and the future? What does modern physics have to say about the idea that linear time is illusory? If our perception of time is an illusion, is it possible to speed up and slow down time at will, including inducing TEEs?
