Do you think my house haunted?

It is very passable but it could be lots of different stuff. As for the house burning down I don't believe in coincidence and if all these things continue I suggest you do what my aunt did in their house when they saw a lady walking in the hall and seeing smoke in the room. Sprinkle holy water in the house and pray and read verses from the bible or call in more Professional help.I don't believe that it could be too dangerous or demonic since it hasn't hurt anyone yet but rather don't take chances. I believe it may just be an unsettled spirit if your house really is haunted.
