ABSTRACT
We live in an age of science. However, there are many types of human experience which continue to defy any scientific explanation, at least in terms of the scientific knowledge that we have at the present time. In some cases we may have a partial explanation, but in other cases the underlying mechanism is completely unknown. These cases which completely defy any normal scientific explanation are referred to as ‘paranormal’ phenomena. In practice there is considerable overlap between what is regarded as ‘paranormal’ and what is considered to be merely ‘unusual’, so this book will review both categories without necessarily making a distinction between them. The purpose of this book is to review the scientific evidence that is available about unusual and paranormal experiences. The main categories of unusual and paranormal experience are listed below, and they will all be examined in detail later in the book.
