Scary Stories ? Please?

I once lived in a house where 3 unsolved things happened to me. I was 6 and i saw this lady pacing back and forth every night in the hallway in front of my room. every night she would be a different colour like red,blue,green,indigo,etc and a few months later we heard from a neighbor who lived across the street for many years that a lady killed herself in there, and that an old man who would play his piano so much that there were groves in the keys. One day he just disapered, along with everything in his house, but the piano. Nobody saw him move or anything. he was just gone. My dad and my brother lived in the house after that and my brother would say "last night there was a lady in the halway and she was orange"
