In my town, there is a huge mansion on the edge of the park, it's open to visitors and people who want to walk through its many rooms, there are tours etc. When I was about 10, my class in school went to look around it one day. As with most big houses, there are ghost stories surrounding it. The story was that a young woman lived there and her father did not approve of her lover so she hung herself in the huge main room from the banister on the balcony. Now you know what kids are like, all the guys in my class were saying they saw a ghost blah blah blah. I didn't really believe it all until I went to use the bathroom. I walked into the bathroom, it was empty and I looked at myself in the mirror and suddenly all the doors on the stalls slammed shut and locked. All of them. Obviously this scared the hell out of me so I bolted out the door and went back to my class. No one believed me though.
I went home at the end of the day and decided I would go back to the mansion on my own and have a look around. I looked through most of the rooms, I had a weird feeling as if I were being watched the whole time. It was very cold even though it was summer. I visited the spot where the woman supposedly hung herself. After a while, I found a circular room draped in red curtains and in the middle of the room was a great big black grand piano facing with its keys away from me. Then I heard music, a slow sad tune issued from the piano and I heard a woman singing, she sang "Servo meus animus vox vocis of piano" I didn't know what it meant at the time, the red drapes began to blow as if there were a high wind in the room, the music stopped and I stood for a moment, then took a pen from my pocket and wrote out the bizarre words she had sung to me. "Servo meus animus vox vocis of piano" is Latin for "Save my soul voice of the piano".
