The possibility of 'time travel' has long fascinated the public. Although physicists tell us such a thing is theoretically possible, any practical application of a 'time machine' will remain in the realms of science fiction for the foreseeable future. However, as this book shows, there are many documented cases where people have been unwittingly transported back, or sometimes forward in time. They find themselves gazing upon scenes not of their era and in some cases dialogue with strangers encountered in the 'time slip' takes place. This book explores a number of fascinating cases and seeks to identify triggers and mechanisms involved in the time slip phenomenon.
