hi all, we recently moved into our house, in the space of ten weeks we have heard bizzare noises in a child monitors, we have had doors open un-assisted, random things totaly vanished, strange shadows on the landing, and to top it all of, we have a safety lock on the outside of my eldest childs bedroom door, 3 times this lock has been opened, by neither my husband or myself, and my daughter has wandered the house ( which isnt safe for her if everyones sleeping), am i going mad or should i be looking further into this? and what on earth can i do!!
