When my boyfriend and I first started dating, I was having dinner with his family; waiting for dinner to be served and idly looking around the house. The dining area is located in front of a staircase that leads up to the second floor of the house.
When I looked up at the staircase, I saw an old woman with faded hair; she was hunched over and seemed to be on her way down. I kept waiting for the other members of the family to call to her and tell her dinner was ready, but since nobody did, I assumed she was a visiting relative and dismissed the whole thing.
Months later, I casually mentioned the old woman to my boyfriend, asking who the old woman was. He looked confused, and I described her as I saw her. Freaked out, he asked what she was wearing. I said long house dress in a paisley print.
He then went to his uncle and asked if any of their relatives stayed with them during that time, and when his uncle said no, he really freaked out and said that I saw his grandmother who had died nine years ago in that house.
A year later, they moved to another apartment and I saw old family pictures that I hadn't seen when we were at their old house. When I saw his grandmother's photo, I knew for sure that she was the woman I had seen.
