Nightmares

It starts off with a girl named Roxianno Mallow or as most people call her, Roxy, a fifteen year old girl. She starts having these nightmares about a man in a black cloak coming out as a shadow from under her bed, going across her wall then coming out and materializing into a humanoid figure (demon thing) and killing her parents, and brother.The demon (whose name Is unknown at this point) then says something but gets sucked back into hell before he can finish his sentence. Every night she has the exact same dream but the demon will always continue the sentence where he left off the last time. She always wakes up with a jolt but doesn't scream, she instead goes past her little brothers room (who is two years younger than she is) which has glass doors to see if he is still there(the bodies disappear after he kills them in her dream, sometimes she can move dreams and follows him). She doesn't tell anyone about these dreams but her two best friends, Ariana Falat and Jersey Wolfram. They have a group chat and she always texts them when she wakes up from her nightmare, and because sometimes she has a panic attack, as losing her family is one of her worst fears, they always calm her down. They don't live far from each other so they always meet up before school and walk together and walk home as the school isn't far from where they all live. Eventually, she starts acting weird because these nightmares do truly terrify her, and her family notices. They ask her but she always said shes just stressed out with high school, and since she's a pretty good liar they believe her. One night, she woke up from someone in her dream telling her that her time has come and she should prepare herself. She woke up only to live out her nightmare. The demon killed her family, and this wasn't a dream. The demon came back into her room and said "Now let's see if your really as strong as you are made out to be" evil laugh then gets sucked back into hell.
