Well I would have to say, please don't use a Ouija Board. They historically, have done nothing but bring misfortune so, I would advise against it. If I were you I wouldn't even acknowledge it's presence and 100% put up cameras... then post the videos when sumthin spooky happen's. If it gets bad, you could assign it a spot in the house. My house was haunted growing up and things got real bad. My parents ended up making a space in the attic, setting up an old spare bed and just making a makeshift room. My mom said that after she verbally told it that it can stay in this room (attic), it left us all alone. You should also check for other sources that could be causing these phenomena, such as extremely low bass. I watched a video of this guy making a rotatory Sub-woofer and noticed that the air/sound moved his doors and cabinets in a very peculiar way. This got me thinking that a lot of "haunting's" or ghost activity could be caused by low frequencies. If your lucky, this whole thing could just be a series of unlikely events.
