Prisoner to the Demons Inside

For AvengingDeanandSam and her contest, hope you enjoy! Drowning in her own body, Carter Finch is accused of a murder she did not commit. Willingly, at least. Carter has been possessed by demonic forces and is detached from any control over her own body. After murdering a loved one, the demon inside goes after two brothers named Sam and Dean. Carter is done with being a demon's play toy and needs to warn Sam and Dean. Somehow she manages to expel the demon from her body and sets of to find these oddly important boys. But the demon still plagues her in her dreams, reminding her of its promise.
"Stupid bitch, you cannot stop me, I will keep killing. After all, people die every day, what's a few more added to the flames? You are prisoner to me, to everything I do, or shall I say... we do?"
