Well,this story is passed on and has really happened!!! were i used to live .. it was a old house about 150 yrs old. it used to be part of the underground railroad. my parents always used to hear my sister talkin to someone.she used to tell them that "a lady always comes and tells me stories" so one night, they decided to stay up and find out who she was talkin to. so they stayed up and they peaked through her door when they saw a lady that looked real, but whiteish-clearish color. And thats not all. When my grand-ma was still alive, she would tell my dad she could hear a pianist coming from the upstairs.. but we had no piano. so my dad went upstairs he said he could hear the piano coming from downsatirs. they continued to argue .. but their is still no explaniation from were the noise came from.
