Prompt/Idea 1

So idea/prompt one
What if Dream was possessed, got released from prison,
and got exiled, but nobody realized he was possessed until
a few years later? They then start searching for him, but he
believes that the demon possessing him was right. The
demon lied to Dream by claiming that they knew he was
possessed and would only let him have control during
fights or when someone was yelling at him. Dream is
confused and doesn't know what's going on
