When I was very small, I liked to listen to the bed story and my sister always told me horror stories. I would be very scared but fell asleep soon. In my mind, when night came, the ghosts would come out and we should not go out of the house, otherwise we would be taken away. As I grow up, I learn the science knowledge and I realize that there is no ghost in the world. It is said that the ghost exists in someone’s heart who has done the bad things. And some older people are superstition. They have the old mind and they know less about the science. In the future, science will dominant the trend.
