Would this freak you out?

Okay so I have NEVER believed in ghosts or anything like that but lately stuff is happening in my house I can't explain and today Rachel (my 6 yr old) told me something kind of scary.

Last month i was tucking Rachel into bed and her closet door seemed to close on it's own. Rachel saw more than i did but she said it had done it before...that is against the gravitational pull to open on its own.

A few weeks ago, dh and I were talking in the kitchen. We have a long hallway that goes to all the bedrooms. We heard something run loudly fast down the hallway towards our bedroom. He was like "Sounds like one of the kids" even though it sounded bigger. All of our kids were sound asleep in bed and we would have seen them going into their room from our room...we didn't.

last week we were in bed falling asleep. We heard no footsteps or anything in the hallway. We have a door that is like a french door but thinner, kind of like the old closet doors. The bedroom door was struck loudly and it rattled. Joe jumped up and opened it and nobody was there. After we got back  into bed, something "fell" off of our dresser that we both swore was firmly on it. It honestly sounded like it was knocked off.

This morning, I was sleeping in and Rachel ran into my room telling me she was so scared. She said she went into the living room looking for something and she heard whispering. I asked her if she could understand it and she said it told her to "Get Out" I ws like "could it have said anything else? she said no and when i asked her if it had happened before she said last week, she had been in bed and she heard a voice tell her "be quiet, I wont hurt you" Rachel is an honest girl, she doesn't lie to me and i can tell she was honestly scared and telling me what she thought really happened.

I'm getting a lil freaked out and I am really hard to freak. Has anything actually happened to anyone else? I am hoping I guess it doesn't get any worse.
