Furnace Troubles

The basement in my friend’s house is one of the scariest ones I have ever been in. I am not one to believe in haunted areas, but this basement has some paranormal activity for sure. Before we moved out on our own I would always stay at his house when we would go out to the bars, and could barely ever sleep. There would be constant creaking and movement coming from downstairs. I never felt threatened, but I did keep a flashlight next to the couch whenever I would sleep over. However, my friend always laughed at me and  tried to convince me that it was only the furnace turning on and off. I never believed him, especially since I never heard his furnace make such noises during the daytime. On one occasion, I woke up in the middle of the night to a loud bang coming from the same area the furnace was in. It woke my friend up too and we had to grab flashlights to go downstairs to check things out. Apparently, a piece of the furnace had rotted out and completely broke off the main unit, causing the loud bang. After we looked at the furnace in the basement, we could see that something was clearly wrong. He had to call an HVAC company just to come repair the broken piece the next day. Luckily, he didn’t have to go too many days without heat. To this day, I don’t think the piece broke off because the furnace was old, I think it was paranormal activity.
