Gaslighting is used to gain more power and control by making you question your reality. It happens much often than you may think and, if done consistency and with an intent to misrepresent the truth, can lead a "gaslighted" person to feel very confused about what is real and what is not, as well as harm their ability to think, remember and make their own decisions. Anyone is susceptible to gaslighting; indeed, it’s a common technique of abusive partners, narcissistic dictators and cult leaders. It is done slowly and deliberately, so the victim doesn't realize how much they've been brainwashed. For example, in the movie Gaslight (1944), a man manipulates his wife to the point where she thinks she is losing her mind.
