Supposedly, the house had a history that was tied to the afterlife in some way. The family's encounters were so disturbing that it eventually led to the story being made into a movie, with the aim of sharing their spooky experiences with a wider audience.
The 'Haunting in Connecticut' is indeed a true story. The family who lived in that house faced numerous inexplicable phenomena. For instance, objects seemed to move on their own, and there were feelings of being watched all the time. The family members' health also seemed to be affected. They felt an oppressive atmosphere in the house, which they believed was due to the fact that it was once a mortuary. This led to a lot of investigations into the paranormal aspects of their situation.
