Of all the supposed real-life haunted houses out there, few boast as much evidence of paranormal activity as the exorcism house in Gary, Indiana. According to witnesses, a real-life version of The Exorcist happened after Latoya Ammons’s family moved into their new home in 2011. Shortly after Ammons, her mother, and her siblings moved in, frightening things began happening. In time, Ammons came to believe her family suffered from a plague of hundreds of demons.
