I married into a demon-conscious family, so we suffered regular "attacks." Most of those were silly things like feeling a tap on the shoulder (probably a muscle spasm).
There was one incident that I've never been able to explain. When I was a newlywed I was home alone in our second-floor apartment and heard someone come up the creaky wooden stairs right outside my door.
There was a third-floor apartment, but whoever was out there didn't go up to the third floor. They didn't knock on my door or go back down the stairs either. I was terrified. Who was lurking out there?
The phone was across the kitchen from where I was standing, close to the door. I grabbed a knife and lunged across the room and grabbed the phone. I called my husband and asked him to come home. He did, and there was nobody out there. Spoooooky!
