Jim, regarding the thermostat...put in a baby cam and see if she is changing it and just not realizing it...on another note
in 1887 a man was sent to prison for killing his wife. A "ghost" told her mother that he had killed her. She pestered the sherriff and they exhumed the body and found she had a broken neck . He was arrested and was tried and sent to prison. His Family never thought him guilty. He supposibly died in prison, but there is also a school of thought that another prisoner died, and he got sort of swapped out with a different identify. Google The Greenbrier Ghost or the book The Man Who Wanted Seven Wives if you are interested...I don't know if they still do, But the theatre group in Lewisburg WV made the story into a play. I watched the play. I read the news stories. I read the Book in which family was "misquoted" according to My Aunt who was interviewed. The man in question, "Trout" Shue was my grandfather's uncle.
