In all seriousness, have you ever encountered something beyond the natural?

I know there are things among people, unseen, and are defiantly there. Like whispers from things I can't see, and things moved by something you can't see. I was wondering if anyone has this happen to them (no, not like the movie Paranormal Activity.) I hear noises that cannot possibly be made by someone or something near me. And before you start thinking my dome has cracked or that i've lost it, hear me out. More than 20 people who have been in this home have experienced things that cannot be explained. Like chains being drug across the floor (before the walls of the home were raised), seeing doors slam, footsteps, our names being screamed by something ( a mans voice, womans, etc.), and deep sighs being heaved near our backs. Uberr disturbing, (but not threatning , I think.)
