Aliens, ghosts, and cryptids may all fall under the category of "strange" or "unusual," but all are classified as paranormal. There are plenty of spooky and scary stories throughout history. From Abraham Lincoln's doppelganger to the mysteries of the Bermuda Triangle and even the feeling of dj vu, there are many unexplained phenomena. Even some aspects of history itself are still a mystery, like the Antikythera mechanism found in a Greek shipwreck. This book shows readers that there is often a blurry line between fact and the paranormal, and sometimes fact is even stranger than fiction!
