I'm only 14, and I don't understand why I'm having dreams like this. It's been recurring for about six months, and I want to understand it in hopes that it will go away...

In my dream, I am in school. A tornado is in the area, and everyone rushes to a dark, cramped room without windows or light. Having been raped nine months before as my dreaming self, I am in quickly-progressing labor and am very afraid, so I tell a teacher. This teacher despises my guts in real life. To my surprise, she is gentle and kind, acting almost as a mother. She takes me to another room, and for a very long time I labor with her assistance. Finally, just before delivery, I die in agony in her arms. As I am a teenager, and have never had a sexual experience, or, consequently, have never been pregnant, I don't understand this dream. The dream is not focused at all on the tornado; it is focused mostly on the relationship of myself and this teacher, as well as the terrible pain of labor. It is very realistic, almost like a memory. I don't know why this dream keeps recurring. This teacher has been abusive; a long time ago we were close, but that ended. I thought I was over it all, and I don't even know if that has anything to do with it. Frankly the dream is upsetting and I don't know what it means or how to make it "go away." Thank you in advance for any help!
