The horrifying real life 'possession' of Anneliese Michel
Licking up her own urine from the floor, possessed by six entities including Hitler and Lucifer himself, and bound by chains as priests battled to save her soul - Annaliese Michel's shock death was the basis of 2005 film The Exorcism of Emily Rose... but they didn't tell the whole story.
It's not often that true events are more unsettling than the horror films they inspire... but that can't be said for the case of Anneliese Michel.
