A woman told her daughter a strange story from when she was 18 years old. She was walking at night with three sisters on a dark road when they saw a black horse enter the trees in the distance. As they got closer, they realized someone was riding the horse but couldn't see well due to the darkness. When they got near, the horse suddenly disappeared among the trees as if it had vanished into smoke. The unexpected disappearance of the horse in the dark trees frightened the woman and now makes her reluctant to visit her old home.
