About eight years ago, after a sleepless night, I decided at 6am to get up. I went into the living room and sat on the sofa. I then looked towards the far end of the room, and saw an elderly lady standing next to my wall, and looking at a painting hanging there. Shocked, I said "who the hell are you?" She looked at me, and said, "I'm Mrs. Day." She then looked back to the painting and disappeared. I knew that the owners of my home before me had been an elderly couple, called Mr. and Mrs. Day.
Later, describing what had happened to neighbours, they confirmed that the clothes I saw Mrs. Day wearing were ones she wore, including the large glasses I saw her wearing. I have seen nothing before or since, but the memory will remain with me always.
