I think my house is haunted....?

Do some web surfing, find something like TAPS (you know the show about detecting ghosts). You are not the only family to have went thru situations like this. It may be something simple and not an actual haunting. But if what all you said above is true then you may have a problem. One that can be solved - who knows. I have experienced things before and know others that have too, so I can't offer you a solution but I can comfort you with the fact that you are not alone. One of the quickest and easest things to try first is to have your local priest, or higher religious person in town bless your home. This may fix it or pacify it for a while. But seriously look into a group that can come and scope your house out and see what they can find. Good luck...I really mean it!
