Haunting from deceased family members.
Can family members spirits be in a house they had never been in? I think my grandfather is in my house(he passed away 12-11-04 and we purchased our house 10-13-2006). There is no history of prior hauntings or deaths. I have furniture that belonged to my grandparents and nothing had ever happened until May when we had moved this furniture in. Doors opening and closing, my dog barking ferociously at a doorway where no one was, footsteps on my back deck to my window and no one there. There is more to the story but this is a condensed version. I have motion dectors outside of my house and the windows are not seen from the doorway my dog was barking at. Can furniture be haunted? I don't have all my grandparents furniture in order yet, and I am thinking maybe that is not letting him rest.
Any help would be appreciated.!
