This happened to my Dad some years back. The house my parents were living in was a two bedroom house. There was a small patch of grass in the front of the house and the veranda was just two steps from the front gate. When visitors arrived during the day, they always walked to the back of the house and knocked on the kitchen door. However when visitors arrived after dark, they would knock on the front door which was very close to the street.
One evening at around 20:00 my mother got into bed. My father joined her a few minutes later. They weren't in bed more than five minutes when to their complete surprise they heard a knock at the kitchen door. My father, although somewhat concerned, got out of bed and walked out of the room toward the kitchen at the back of the house.
Somehow my mother also had the feeling of 'foreboding' and called my father back to the bedroom. She said 'dont open the door, first ask who is there'. My father replied that was exactly his intention. Then he turned and left the room again. As soon as he walked into the passage he felt what seemed like hands on his elbows, lifting him entirely off his feet. He was carried down the passage, through the living room, toward the kitchen. He recalled that out of absolute fear he was shouting at the top of his voice, yet there was no sound coming from his mouth!
Once he was in the middle of the living room it felt as though he was being pushed from behind by whatever was carrying him into an invisible wall. Something (or someone) was stopping him from being carried any further. Suddenly he was let down ever-so-gently back onto his feet. He never made it to the kitchen door.
He turned and walked right back to the bedroom. My mother recalled that when he walked into the room the sweat was pouring down his face and there was no colour in his face. When he lay down the bed shook for quite some time before he could calm down and tell her what happened. They never found out who was their night visitor.
