A story from the housing complex where I lived as a child.

The housing complex where I lived as a child was a 5-story building with no elevator, and two rooms faced each other across the stairs. Due to the room structure, one of the inner rooms was adjacent to one of the rooms in the opposite apartment, separated by a single wall. After starting elementary school, that innermost room… the one adjacent to the opposite apartment's room by a single wall, became my children's room. At that time, a refined elderly couple lived in the apartment across the way. The husband worked and was out during the day. The wife seemed to spend her days alone. One day, I noticed something strange. On the wall adjacent to one of the rooms in the opposite apartment, a faint face, like the 'Greys' I'd seen on TV, was appearing. At first, I thought I was imagining it. But as the days went by, it became clearer and clearer. It looked like a human face. When I told my mom, 'There's something like a face on the wall,' She came to look, saying 'Let me see?' but just laughed it off, saying it was my imagination. She also told me not to worry about it. A few days later, my mom said, 'The face on the wall is gone now, isn't it?' When I looked, it was indeed gone. When I asked why, my mom just smiled. To be continued
