The Stair Case.
My friend and her husband moved into a dilapidated 1920's house which we all helped to restore to its former glory, so we were round there a lot when they were doing it up. Everyone said they felt a little bit strange on the stair case, like there was someone watching us as we went up and down, although never in a bad way.
They had been living there about a year when one of the neighbours just happened to drop into the conversation that there had been an old lady living there previously who had had a terrible accident on the stairs. She used to have dogs so had a wooden stair gate at the bottom to stop them going upstairs. Apparently she slipped on the stairs and broke her neck on the stair gate. She wasn't found until a few weeks after this by which time she was dead of course.
None of us knew of this story when we were decorating the house but all of us felt that there was something about the staircase. I believe that spirit of the old lady was staying to warn other people in the house about the stairs so we decided to hold a candle lit prayer night for the old lady asking that she find peace and also promising that we would remind everyone to take care on the stairs. Funny thing is, the watching feeling disappeared after that night so we think that she did indeed find peace at last.
