Soo... now you can't write from your imagination without it being called " Satan helped me"? That's like saying artists and authors alike are channelers or satan worshippers because we write and draw from ur imagination.
Sometimes you can't help but not feel the need to finish something.

Yes, in todays world there are such things that could've came from being possessed or channeling from the spirit-realm... however things like writing is basically like art, it comes from your imagination. I've had dreams that inspired me to draw and write before. It's not that uncommon for someone to get the inspiration from dreams.

Personally I think it's only evil if you percieve it as such, in this case. But then again... I guess this is why I'm not that religious and roll my eyes at things like this. I could understand that some music having been influenced but not written works or even art, because that comes from the soul and your imagination.
Even if I had seen that episode of Doctor Who where Shakespeare gets possessed... which this thread does infact reminds me of.
