About  three years ago,I watched a horrible movie.I made a nightmare on that night.I dreamed I was lost alone in the woods,walking for a long time,afterwards,I not only heard strange growling sound but also saw a girl in white with long hair.As I approached the girl and asked the way to her.I saw that she was a ghost.At that time,I was frightened and ran away,and she ran after me.I did not awake until I fell into the mountain valley.Originally,this was a nightmare.
