... or might need it, the 1999 revised Catholic church's Rite of Exorcism
I've always thought the whole heaven/hell god/devil thing was hokey at best, but I do think 'demonic' possession or encounters occurs. My take on it though is some people wallow in so much negativity and hatred that they anchor aspects of their personality or psyche here after they die, and that's what us live folk are encountering when things like this pops up.
Having spent a pretty decent amount of time at Bachlor's Grove cemetary I have had some experience with what may very well have been 'If you've convinced yourself, that's great' but sure as hell felt like something strange and possibly malevolent. Because of this I have had a pretty voracious interest in this type of thing for sometime. However, having spent the last 48 hrs. relaxing at my in-laws house in beautiful, lush Defiance, Ohio I've just caught my yearly share of cable tv and what I noticed was that shows about 'hauntings' and exorcisms must currently be all the rage. This may very well have to do with the fact that horror in general has been popularized as the 80's generation that grew up sneaking to watch 'Howling', 'Halloween' and 'Friday the 13th' have become the foundation of the consumer force. Icons like Ozzy Ozbourne do not freak them out, and the things their kids are exposed to do not have to be so squeaky clean. Thus, Mick Harris can jump from the popular HBO series Masters of Horror to NBC with a prime time series, horror movies gain a massive standing as viable box office lures for all ages and things like the stale and cheesy 'Ghost Hunters' and the just plain awful 'A Haunting' litter the daily line-ups of up and coming cable stations. This kind of pop culture exposure steals legitimacy left and right from investigation or conversation of the probably hundreds of possibly legitimate claims of paranormal happening throughout the country and the world. Ten years ago if you punched words or phrases like 'ghost hunters' or 'Haunted places' into a search engine you received links to some pretty voluminous articles. Now its all links to products and shows.
Looks like the spectacle will get us - even after we're dead.
