I live in a small town in California. It is a mining town with a lot of history. I've known for quite some time my house was haunted but when my dad started dating this girl, things started acting up a lot more than usual.
She has to kids who were also interested in the paranormal. Anytime her or her kids were there things such as the sink would turn by itself or we would hear random noises come from my attic where most of the activity is. The two kids (Conner and clay) grandfather was a cop in his younger years. He had told us that a while back he knew the owners of the house who had both been found dead in the house. He even said that he was one who took the bodies out of the house, so he was shocked to see the house when he came over to pick up Conner and clay. We wondered if that's what was causing the sudden increase of paranormal activity.
About a month went by and he came back to drop the boys off and he brought a belt with him that belonged to prior owners who had died. During an evp session we asked the question "Is there any one in this room with us." we caught a male voice saying "yes" followed by a deep deep voice yelling "no." From then on we started getting scratched and pushed and other things of that nature. We then thought it could be demon or something. We got a hold of holy water then blessed my house. When we blessed the attic we heard a growl that lasted about 8 to 10 seconds long. For the next few month everything stopped but every once in a while a door will shut by itself.
