Guess who's starting a new book?

I got the idea for a horror/mystery story and the plot just rolled naturally. I don't know when I'll start the writing or just how long it will be but this is what I have so far.
"It dark and cold, my mind says it should smell musky, but I can't breathe or move. If I knew it would be this lonely I would have been cremated."
"'I can't sleep' she whispered as she crawled into my bed. I woke with start my body cold as I clutched the dress she was buried in."
She woke up dead and buried. She find her way out and her way to him. She doesn't know why she can't sleep but she thinks it's because her murder is running free. How does a ghost solve her murder if no one can hear her?
He hears her, he feels the cold she brings and her icy fingers caress his cheek. The police said it was suicide but he knows her, he know she wouldn't take her life. He know she's here because her soul can't sleep because she was murdered and no one knows it but him. Why can't she say anything besides "I can't sleep,"? How do you solve a murder everyone has ruled a suicide, when your only witness is the the dead victim?

Ugh

     I've had a rough few days as a mom and as an author. I found out some pretty embarrassing issues with my novel. I thanked the wrong person in the acknowledgments, i forgot to number the pages and 'monsters' was spelled wrong on the COVER! That's on the author side of things.
     On the mom side of things, my daughter has become pretty aggressive with her cousins. Separating her from them when she's aggressive works for a little bit, but soon she forgets why she was separated in the first place and starts all over again. But on the bright side she's been eating healthier foods with little fuss, YAY :D . That's all i have to report for now thanks for reading :D
