You BELIEVE it brings up things in the subconscious. You BELIEVE they then disappear by repetition. The 35 people killed in 11 post office shootings by postal workers who went nuts doing their repetitive jobs may disagree. They thought shooting everyone up would make it disappear, but that didn't work, either.
Seriously, though - repetition is harmful and there are hundreds, maybe even thousands, of research articles over the last 50 years all over the world to find ways for businesses to eliminate repetition because it makes people zombie-like, unhappy and they make mistakes. Your beliefs are not supported by any research.
The Catholic church used to sell that line of bull, too. It also relieved the congregation - of money. Hundreds of years of exorcisms and still no medically or scientifically documented cases of possessions and successfull exorcisms (cures) ought to be a clue (you'd think).
I'm not surprised you're saying that. They say a sucker is born every day. "Psychic" con-artists have taken money from the grieving and mentally unstable for centuries by claiming to contact their lost loved ones, rid their homes of evil spirits, etc. Some people will always believe they are controlled by unseen spirits and be gullible enough to pay someone to get rid of the bad ones or contact the good. As I said above, it's a very old con.
That's really dark. The Marquis de Sade would completely agree with you:
"the Marquis de Sade offered a wholly different view - which is that pain itself has an ethics, and that pursuit of pain, or imposing it, may be as useful and just as pleasurable, and that this indeed is the purpose of the state - to indulge the desire to inflict pain in revenge, for instance, via the law (in his time most punishment was in fact the dealing out of pain)."

You do know who the Marquis de Sade was, don't you TomKat? He was a very famous sadist who imprisoned and tortured women. You might want to reconsider your philosophy about inflicting pain on others being "good" and "beneficial."
