We have lived in haunted homes, only once did we feel evil in one. It was when we were moving out, strange things happened. But the house we moved from last, we both felt a weird sadness when we left, like the house was sad. But in one house, we had a sofa in front of a sliding glass door to a back deck. I would be sitting there reading, and I would feel a tap, turn around, nothing there, tap again. I would get up and move to a chair, the tapping on the shoulder would stop, just weird stuff. A man in a loud sport jacket, right in the middle of the great room, then he was just gone. We later found out that a salesman had committed suicide on the dirt road that ran by our house, they found him in his car by the cornfield nearby, monoxide. It happened about 12 years before we moved there.
