After thinking about The Exorcist in the earlier post, l have been reading about Exorcisms, and in particular, the Exorcism of Anneliesse Michel (and the ensuring prosecution). The above clip has tapes from the Exorcism (which went on for months) and some photographs of her. The film 'The Exorcism of Emily Rose' is loosely based on the events, and there is still a lot of debate as to whether she was possessed, if the priests and family did the right thing (she dies of dehydration and malnutrition), and if she should be classed as a saint.
To me, much as l love the films, the demonic stuff is all rubbish and she suffered from a mental illness (probably Depression and Dissociative Identity/Multiple Personality Disorder). The priests and family failed her insomuch as they did not provide (as we say in the trade) a 'Duty of Care', resulting in her death. It's still interesting hearing and seeing Exorcisms, just to witness the sheer (and unwarranted) belief that the 'victim' is possessed. Maybe she was prepared to do anything just to get some attention (that is not an official medical diagnosis). Once again, l blame God.
