...center of the room? I don't believe in paranormal. I don't sleep walk. I have lived in this house 10 years nothing like this has ever happened. My girlfriend confirmed the chair was 100% not there before we went to sleep. I'm certain there is a reasonable explanation.. but what is it? And no this wasn't a prank by my girlfriend. She is honestly freaked out badly. Hence why I'm on here. Neither one of us left the bedroom last night the door is shut and is very loud when it opens. We are both light sleepers and one of us would have heard it. Please let me know a scientific explanation....please.
