As many of you know, I've had 'hauntings' at my house for a long time. Lately, it has taken the form of hearing demonic voices speaking in my ear as I'm waking up.
I totally sympathize with you. I've personally experienced demonic possession of a house (including poltergeist activity, with kitchenware flying around the house and smashing against the walls) and a disembodied voice which several people heard simultaneously... It was very, very frightening.
I was a sheriff deputy at the time, and this was my third response to a house in a month, where the homeowner reported he had discovered the front door standing wide open in the middle of the night after he had locked and bolted it. When I walked in the third time, not only did all Hell literally break loose, but the disembodied voice addressed me by my first name, which was totally horrifying, since I had never used it with this guy, and only my last name appeared on my uniform name tag.
The more I do the Rosary, the less these things happen. So, I feel that through prayer, church attendance and the Rosary, I'm making headway against these demonic forces.
Yep. The third time I responded to the house.. I brought a Bible and a crucifix with me, and I started reading some verses I had preselected which rebuked the Devil... and everything stopped immediately. I informed the homeowner he had just 15 minutes to pack up his belongings and get himself and his family out of there.
While emptying the bedroom closet, a Ouiji board was discovered. "Are you kidding me" ?! "Are you insane" ?.. I shouted ! I kept the infernal thing and dropped it off at a Catholic Church the next morning for proper disposal.
I was going to toss it into the burn barrel in my yard and incinerate the thing the next morning, but something told me not to. I later read on-line on a website that burning artifacts associated with demons is ill advised, because fire is often used in many satanic rituals. The Catholic Church has established protocols for disposing of dangerous artifacts, and I shouldn't have been surprised at the seriousness with which the priest took possession of the Ouiji board.
I recommend, you first make a thorough search of your house. Get rid of anything suspect... there may even be something there you are unaware of... like something left behind by a previous tenant. Since you are a Catholic, I don't have to warn you about "Santaria" (A mixture of Caribbean Voodoo and Catholicism), in which Christian artifacts are routinely substituted in rituals for dark gods and demons. You may have innocently come into possession of such an artifact.
If there's anything in your house (Christian religious relic, or otherwise) and you don't know for sure where it came from... get rid of it. Anything like that can be easily replaced.
