It was called the Maneating Fog. The people were never seen again and no one knows what exactly happened. In my Grandmother's house, there is a small room that had a bed and a small dressing table with a mirror. This only happened when there were only females in the room. The girls would be seating on the bed, talking about the things.
Girls talk about to other girls.
All of a sudden, one girl would notice something in the mirror. There would be a stocky, grey-haired lady smiling at us. This happened many times.
