You may not want to watch "Paranormal Witness" alone if you're easily spooked. This series brings to life -- through the use of first-hand testimony, home videos and personal photos -- the stories of people who have lived through paranormal experiences. In addition to featuring the usual paranormal stuff -- UFO sightings, poltergeists, haunted mansions, to name just a few -- "Paranormal Witness" episodes also tell the stories of a child with an imaginary friend and a highway that is said to be haunted.
