During the filming of Gods and Monsters, the cast and crew spent time at director James Whale's former house. Apparently, after his suicide, his ghost remained on the site. The new owner called in a priest to have his spirit exorcised and removed from the property.
Sir Ian McKellan's response was well put: "And why the fuck did you do that?"
Can spirits truly be swept from a home like a pile of ash? And if it is at all possible, is it morally objectionable?
Personally, I abhor these notions. I have never evicted a spirit nor do I ever intend to do so. I don't feel it is my right to march into a property and tell a ghost they need to leave. Why do people think it's some form of standard protocol? In our throw-away society, we tend to get rid of the things we fear or feel there is no need to keep. Ghosts happen to fall into that category.
When confronted with an individual dealing with a haunting, I have been asked to "remove" a ghost on several occasions. Every time, I have turned down the request. I simply tell them to treat the spirit like a roommate. Lay down ground rules. Reach an understanding. Just like living humans, if you acknowledge their presence and politely ask them to cease and desist, they often oblige.
Now, I know people will tell me that in cases of "demons" or evil entities, they need to be removed. First, I have never encountered something I would deem "demonic", though I have encountered some rather nasty ethereal individuals. I have no qualms with investigators trying to rid clients of these forms of bad dead people. Such cases are extremely rare, though, so the average spook in your attic isn't something to be feared.
We have a tendency to misunderstand spirits. Bangs, footsteps, and moving objects are treated as personal attacks, when their real meaning is often benevolent. They are cries for attention and acknowledgment. A simple "I know you're here, but please leave everything alone" normally stops such activity. Coexistence can be peaceful. There is no need for overreaction.
I do hope that Whale still lingers at his old homestead. Perhaps he simply quieted down to avoid another personal assault. But the thought that he packed up and left after a few splashes of holy water is absurd. He wasn't some evil entity. He was merely a sarcastic, humorous man. His personality alone wouldn't let him give up without a fight.
If you ever happen to find yourself in the midst of a haunted house, ask yourself why you would want them to leave. Are you really that threatened or are you just behaving irrationally? Most of us dread living in solitude. A little companionship, living or dead, could make for some interesting times.
