In addition to the obvious meaning of "gas-powered lighting," a very common type of psychological abuse is said to "make gas light" where the victim suffers permanent bullying-like harassment that makes her feel insecure about herself and even dependent on the abuser. It occurs in family or couple relationships where those who make gas light disparage, devalue, isolate and manipulate their victim until they lose all self-confidence and are unable to realize that they are being violently and psychologically, remaining in a state of helplessness and total dependence on the abuser, whom she sees as a person who protects her from her own incapacity. The English name is gaslighting, inspired by a 1938 Patrick Hamilton play, which is set in Victorian England, where a widower and remarried searches his mezzanine for jewels that his first wife (whom he murdered) hid and so that his current wife does not suspect begins to create situations in which she ends up doubting her sanity , saying that he does things that he does not remember afterwards or that what he sees is not real; all in order to kill her too, faking a suicide by dementia. Six years later the film version Gaslight directed by George Cukor appears which is the one that ends up popularizing the name gaslighting, and in Spanish 'gas light', because in the argument the husband turns on the gas lamps of the mezzanine and the wife sees the lighting go down in the rest of the house, but he denies it saying that she is crazy , which is your imagination and that the light of the house never changes.
