I have had very strange occurrences at my house!
Well, I have lived in my fairly new house for about 2 years and very strange things happen... for instance, the volume on th TV changes constantly, one time I was in the basement by myself and heard heavy footsteps above me in the kitchen(and my cat is only six pounds so it could not have been her) and then five minutes later my family comes home, another time last year I was upstairs and laid a bag of candy outside the bathroom and when I came out it was ripped open and my dad was two floors below me and all I heard was the bag opening when I was in the bathroom-no footsteps, and I constantly see shadows and see shapes/figures in the TV reflection that aren't there when I turn around...
Oh and also I hear footsteps advancing the stairs constantly when I am the only one home and I have heard a man coughing in the basement when the only ones in the house are girls... plus something is touching my back as I type! HELP!
p.s. there is an vertical tunnel in my basement behind a cover in the wall that drops about 30 feet below my house and is fairly wide-wide enough for a human to fit in... do you think that could have anything to do with it? I need some answers!
