A family friend of ours lives in a haunted house in Montana. Her ghost is quite mischievous too. Its stolen a can opener and returned it several days later, its held a door closed for 30 minutes while someone was inside trying to get out, and according to her its held a party in her living room with loud music and voices. Ive tried to get her to contact the Ghost Adventures crew or a ghost specialist but shes refused. She says as long as its not violent shes fine with it. Thats probably the kind of ghost Id be, mischievous and fun.
