Back in the 1990s I worked in an old cotton mill in my home town of Oldham in the city of Manchester. One night I decided to go and have talk to my brother who worked on the floor below mine, so I went out onto the stairs to go down to visit my brother.
The building was quite old about 120 years old or so. Anyhow, after chatting for a while, I said to Marc (my brother) that I'd better go back to work. I went back out onto the stairs and closed the door and as I did I could hear footsteps coming up the stairs from below. I must mention that the stairs were made of stone, so you can imagine the sound of footsteps as the feet slide on each step!
I thought it was a friend who had a habit of using these stairs so I waited for him to come up as the footsteps sounded like they were just round the corner! After a few moments no one appeared so I went down the next flight of steps, but the sound of the footsteps again sounded just round the corner. I waited just a few seconds, then went all the way back up to the top of the stairs! All the time I could hear the footstep coming up. I tried to be brave and waited for about 30 seconds but no one came up!
By now I was at my own work floor so I went inside took a few paces into the work room and watched to see who came through the door. No one did!
It was only later that I found out that German prisoners from WW2 had been kept there and had worked in the mill as well! I asked other work mates if they had experienced anything on the stairs but they said they wouldn't use the stairs at night because of what other people had side about strange experiences! So I just wonder if it was one of the WW2 prisoners who got left behind.
