I was sitting at home one night last winter. I was watching a terrible programme on TV and I was feeling bored. I was thinking of going to bed when I heard a strange noise upstairs. There was no-one else in the house so I felt a little nervous. I switched off the TV and the lights in the living room and crept to the bottom of the stairs. I sat there silently for a few minutes. It was cold and I felt scared - I shivered. Then I heard it again. It was a noise like someone crying. I was so frightened I couldn't move. I stayed there for another twenty minutes.
