If like me you are something of a sceptic in all matters 'new age' such as crystal healing and such like you could be forgiven that this book is yet another in that hippy/kozmic wonderland of hype and plain nonsense..not so in this case..the author had worked for some time in the science field before this book..it gives a fascinating insight into as yet unchartered territory of human exeperience.the reason i purchased this book was mostly due to some experiences i had had myself..and even some friends eg of late a friend was even able to locate a particular building with such alarming detail , I even went to the place in London where she described and it fitted exactly with the description she gave me...not bad when you consider she had never been to London in her life. so food for thought there..please read, leave your mind open..and consider the possibilties of such things..
