    As I was watching the end of this, I realized a childhood memory where at the end of the hall at our cousin's home was a full length mirror. I thought it was a door to another room. As I approached the mirror, I perceived my reflection to be another child who was taunting me by walking toward me, blocking my way so I could not go in. I would retreat and saw the other boy retreat at the same time. I can reason now that the perceived door was a mirror and the other boy was my reflection.
