it’s probably an expanding pipe in the walls…they pop when they heat up with hot water…old houses make a lot of noise…it’s just an old house…now, think to yourself…you believed the last house you lived in was haunted too…what are the chances of moving to another completely different house that is also haunted…you shouldn’t believe this…!!
I believe your house is haunted too. I believe in that kind of stuff. My house is haunted too. Don’t be scared though. It’s not a big deal. If you want them gone, get a team out there to help you.
