Have you ever seen a 'ghost', do you believe in the supernatural?

I have never seen a ghost, but I have had a ghostly experience. My mom and I were in the Kitchen and my sister went to the bathroom. A few moments later, we heard her calling and banging. We went in to the bedroom that you had to walk through to get to the bathroom. The bed, a huge queen-size that was VERY heavy, had been pulled down about 5 feet in front of the door, blocking her in the bathroom. No one else was there and there was NO WAY she could have moved the bed in front of the door. It was really weird. We also had heard things like foot steps on the porch and knocking on the window and door when no one was there. It seems that years ago an couple lived in the house and one of them came home early to catch the other cheating. After coming in through a window, the jilted lover killed the cheating spouse. We believe that the ghost of one of them was 'stuck' there in that house. They say that burning down a house releases the ghost, so perhaps when that house burned down the poor soul was released. We were never scared by anything except the bed moving and that wasn't even to scary, mostly confusing!
