If you are interested in UFOs or even other things like that, you have probably at least heard of the Men in Black. This phenomenon is a very interesting(and terrifying ) one. Monsters and Mysteries in America had some episodes about MIBs this past season, and after seeing them I decided to get Nick Redfern's 2011 book on the subject, The Real Men in Black.
The first part of the book is all accounts of people's encounters with Men In Black - from Albert Bender and Gray Barker back in the 1950s to the present day. Even cryptozoologist Loren Coleman had an encounter with a Man in Black in the 1970s. Some accounts have very odd aspects to them, and you may find it shocking(like I did) how they are eerily similar to legends of vampires and Tulpas, which are discussed in one chapter.
Part two of the book is all about the theories of what MIB are. There are many, and each one seems to be able to explain some aspects of SOME MIB encounters, but not all of them. Some are hoaxes, some are honest misidentifications, but some sound like aliens, time travelers, demons, FBI agents, and Tulpas and vampires like I mentioned earlier.
I thought this was a very good book on the MIB phenomenon. I found it to be a great read, and even a little scary at times. If you read the book, it might even scare you a little, too. A must have for everyone interested in UFOs, MIB, and unexplained things in general.
