Spirits In My Home, Just a post about some ghost phenonemon in my home Options

My girlfriend and I, live in a little three bedroom house that was built sometime around the beginning of the start of the town which occurred in the late 1800s' sometime.
Lot's of paranormal stuff happens in our house. Things go missing, the dogs freak out and stare into an area like they see somebody and they shiver like they are having a seizure.
Doors open on their own, without any physical explaination. One time the inside door to our porch opened, then the outside door corresponded. It couldn't have been wind because if it was, the outside door would have opened first, then the inside. Also, it couldn't have been a vaccum because the doors open inward, and the furnace fills the room with hot air. That would techincally cause the door to open to other way if it could. We hear knocking on the door that is plain as day, and we go to answer the door, dogs barking, and nobody is there. Not knicky knicky nine doors either. We can see right up the road and there is lots of snow. We would see footprints in the snow. Also, my girlfriends dad, has actually seen an apparation plain as day. He thought it was me. I wasn't awake. My mom saw a guy, standing on the stairs, and freaked out. There is also a lot of strange energy in the home, and anybody that comes in here asks if we've ever had ghost stuff going on. My girlfriend is absolutely opposed to me having any communication with this spirit, as she feels i should leave it be, but I really want to see it and find out who it is, where it's from, and who it's subject to. My psychic influences tell me that the spirit was the man who built the house, and he died here. But I'm not really allowed to contact the spirit, because my girlfriend is afraid, and morally against it. She said if the spirit contacts me that's a different thing, but i'm not allowed to be the antagonist (IMG:style_emoticons/default/smile.gif)
There is definitely some ghost in out home that want's to be recognized, but contacting it is out of the question. Funny how that happens sometimes eh? The living have precedance over the affairs of the dead...

These kinds of spirits are usually, at first, just trying to get your attention. In my experience with these guys though, they get more and more aggressive as time goes by, especially if you are an occultist and inviting other spirits into your home. Or if you are like me, creating servitors are very annoying to them too.

So, if you want my advice, summon (or pray) to the Archangel Michael and ask him to get rid of any spirits you might have in your home. He will either destroy the bad ones or if it's a deceased soul, he can send them to their next life. I turned to him when I had some very aggressive spirits in my home and he worked very quickly without any "if's", "and's", or "but's".
