Overview
In 2011 Latoya Ammons and her family moved in to a small house in Gary, IN. What happened next would turn into one of the most documented cases of demonic possession in history. The Ammons moved out of the house in the Spring of 2012 after just a few short months of living in the house. Latoya ended up having 3 separate exorcisms performed on her, one of which went viral. The house became known as a Portal to Hell. 
This gained the attention of paranormal investigator Zak Bagans, better known from his Travel Channel show Ghost Adventures. Bagans purchased the house over the phone, site unseen. The next week he and a film crew went to Gary, Indiana to start filming.
Fact or Fake
Through out the document the question gets brought up a few times. Was this all a hoax and just a way to earn some money and fame? At times, some of the people do seem to be very financially motivated, while others truly seem to be terrified and have legitimate experiences to talk about. Bagans does a great job at separating out what is fact from what is fiction used for financial gain.
The Experiences
Since the documentary released, numerous people have reported strange happenings in their house or even in their dreams. Immediately after watching it, our crew all began to hear strange knocking sounds through out an otherwise quite house. One of the strangest things that happened that night was the vision issue that we all started to 
develop. Which is very strange considering that it directly correlates to an experience that Zak has during the final moments of the film. I ended up watching Demon House a second time, and that night I was fast asleep and I had an odd dream. It wasn’t even a nightmare, it was just a simple dream about picking a black dog up off the side of the road. I thought that it was a stray so I put it in my car and drove it to a shelter. When I got out of my car I went to the back to get the dog out. Upon opening, I quickly realized that the dog had died. I woke up out of a deep sleep in a panic. I was truly terrified. Since then I have not really experienced anything else.
Final Thoughts
Overall, the documentary is very well put together. The experiences that happened to Bagans, his crew, the experts that he brought in and several other people all lead to a very believable case of demons. The house may not be the so called Portal to Hell but something was definitely happening there. The facts and experiences far outweigh anything that could have been made up. Even if some of Latoya’s story was fabricated for fame and money, things happened in that house that caused real life-long issues for everyone involved. In all honesty, it is one of the best horror documentaries that I have ever seen.
Demon house is available on iTunes, VUDU, Amazon Video and all other major VOD sites.
