The Exorcism of Emily Rose

Do devils really exist in this world?

Recently, I watched a movie called 'The Exorcism of Emily Rose'. This film is based on a true story. It talks about a girl named Emily Rose being possessed by the devils. There are altogether 6 devils living in her body. They want to take over her body.
Emily Rose was a happy girl once before she got her scholarship to further her study at a place far away from home. One day, she was all alone in her hostel because her roommate had gone home. At 3 am, she smelt something burning there was no alarm, afraid there was fire then she woke up. But she found nothing. She was scared and went back to sleep immediately but she felt a strong invisible strength pushing into her body.
Everyone thought Emily had gone crazy and she was under medication. But thing got worse. The story went on but unfortunately, Emily was dead. Her gravesite has become an unofficial holy shrine which continues to draw visitors form all over the world.

If you ask me whether or not I believe the existence of devils, I would answer I am not sure. But I truly believe that there's another space in this world... If we respect them, they will respect us...
