It was Halloween night so my sisters and I decided to go trick-or-treating. We were very excited. By the time we got to the last house in the street, it was very late and we were tired. The house looked empty, but we knocked anyway. The door opened on its own. Although we were scared, we decided to go in and have a look. Suddenly, we heard a loud noise and a huge creature jumped out in front of us. "Don't be afraid, it's just an owl," said a voice from behind us. We turned around and saw an old lady at the bottom of the stairs. She rushed over and introduced herself. "Hello, I'm Mrs Shade. Let me give you some treats, you naughty little ghosts! "When we finally got home, our Mum was very worried. "Where were you?" she shouted, the moment we walked in. "Don't worry, mum. We were at Mrs Shade's house, you know the big one at the end of the street. She gave us treats and ..." Mum looked puzzled. "What on earth you talking about?" she said. "Mrs Shade died ten years ago!"
