Query: Must read!

I think most people have stayed up late at some point in their lives watching a movie or reading a book about aliens, the unknown or topics of this nature and have had a spooky fear come over them that was hard to shake. For me the moment I most remember was when I was reading the book 'The Mothman Prophecies.' If you have had this fear and want to understand why you can feel it in your bones but can't put a finger on its origin, read this book.
