"Gaslighting is a form of psychological abuse. It uses persistent denials of fact which, as they build up over time, make the victim progressively anxious, confused, and unable to trust his or her own memory and perception.
A variation of gaslighting, used as a form of harassment, is to subtly alter aspects of a victim's environment, thereby upsetting his or her peace of mind, sense of security, etc., such as was used by the Manson Family during their "creepy crawler" burglaries during which nothing was stolen, but furniture in the house was rearranged."
-----From Wikipedia, the free encyclopedia
For those who saw the movie - Gaslighting (released around 1944) would understand what gaslighting is. It is a subtle method of harassment to a person that would cause psychological effect if this person lives in such an environment for a prolonged period of time.
Group stalking, also called "gang stalking" uses the same methods to destroy the perception of a person's normal social and work environment in a hope to wear down this person, or drive him/her crazy. Gaslighting is a process that can take several months or even a year to condition a person's perception of his/her life environment. Once this condition is achieved by repetition of the same type of harassment, the person being gaslighted would lose the normal reaction to the trigger event even though such a "trigger event" might be completely unrelated to him/her. Now he/she is said to be programmed to react abnormally for a certain trigger that would discredit him/her as mentally unstable, or even crazy. Thus, many victims of this organized crime are blamed for mentally ill. The truth is they got disoriented by psychological abuse.
This state of mind is "man-made" by evil perpetrators who attack the victim by lies, and disinformation or misinformation. Unfortunately many people would choose to believe lies and slander, and overtly join the group and give the perpetrators a helping hands because this makes them feel empowered when they collectively abuse an isolated person.
Some survivors of gaslighting went through the deprogramming stage, and gradually got out of this negative condition. It takes a long time to get out of this hideous "program", and more important is to be able to receive supports from society. Money and power is always the controlling factors in this "psyche game" as it all started by an evil person who possesses the power and money, and started slander campaign to vent their personal grudge against the victim. This organized crime is motivated by revenge and punishment only. Don't believe the disguise of the beautiful words or deceptive excuses they tried to fool the public. Only the victim has the right to judge if they did this to help the victim, or to destroy the victim.
For those who suffers this hideous crime, please stay firm and keep strong. There is nothing wrong with you, the sick ones are the perpetrators. All you need to do is to believe yourself, setup a goal, and work hard to obtain your goal. When your mind is free from being disoriented, free from being negatively programmed by them, you will be able to claim you sanity and credibility. You show your power of independent thinking, and your integrity and human dignity.
