Gaslighting is a form of emotional manipulation where someone makes you doubt your own memory, perception, or sanity.
Gaslighting is a manipulation tactic where one person tries to make another doubt their own reality. The term comes from a 1944 film in which a husband slowly convinces his wife she is losing her mind.
In relationships, it shows up as denial and reversal. Common lines include that never happened, you are too sensitive, and you are imagining things, even when the other person clearly remembers events.
Over time, the target starts second guessing their own memory and feelings. They may apologize constantly, feel confused, and rely on the other person to define what is real.
Gaslighting is recognized by mental health professionals as a serious form of emotional abuse, not an ordinary disagreement. The goal is control.
A useful sign is how you feel after conflicts. If you routinely leave conversations doubting yourself and your own recollection, that pattern deserves attention.
Keeping notes, talking to trusted friends, and seeing a therapist can help someone regain trust in their own perception.
