Gaslighting: Meaning, Examples, Signs and How to Respond

Gaslighting is a form of psychological manipulation in which someone repeatedly denies, twists or dismisses what you saw, heard, remember or feel, until you start doubting your own memory, judgment and even your sanity. Merriam-Webster defines it as "the act or practice of grossly misleading someone especially for one's own advantage." The term comes from Gas Light, a 1938 stage play by Patrick Hamilton, best known through the 1944 film Gaslight, in which a husband secretly dims the gas lamps in the home and then insists his wife is imagining it.

Gaslighting is not the same as disagreeing or remembering things differently. It is a pattern, it usually builds slowly, and its effect is to make one person more dependent on the other's version of reality. The National Domestic Violence Hotline describes it as an extremely effective form of emotional abuse. This guide covers the meaning and origin of the word, real-world examples and phrases, signs you are being gaslit, gaslighting by partners, parents, bosses and medical providers, why it works and how to respond and recover. It is part of our guide to red flags in a relationship.

Gaslighting meaning: what does gaslighting mean?

In psychology and in domestic violence work, gaslighting means manipulation aimed at making a person question their own perception of reality. Three elements set it apart from ordinary conflict:

• Repetition. It is a pattern of denials, corrections and dismissals, not a single argument.
• A target that keeps shifting. The issue is never just the facts; it becomes your memory, your sensitivity or your mental state.
• A power payoff. The person doing it avoids accountability, gains control or keeps you from leaving. The Hotline notes that once an abusive partner has broken down someone's ability to trust their own perceptions, that person is more likely to stay in the relationship.

The word has spread far beyond therapy offices. Merriam-Webster named gaslighting its 2022 Word of the Year after lookups on its site rose 1740% that year. Wider use has a downside: people now call any lie or disagreement "gaslighting." A partner who misremembers a date is not gaslighting you. A partner who tells you for months that conversations you clearly remember never happened, and that you are "losing it," may be.

Spanish speakers often use the English word as well; the Hotline's Spanish-language site titles its explainer "¿Sabes lo que es gaslighting?" A common Spanish rendering is "hacer luz de gas."

Where did the term gaslighting come from?

The story begins on the London stage. Patrick Hamilton's play Gas Light (1938) follows a husband who tries to convince his wife she is going mad. He dims the gas-powered lights, and when she notices, he denies the light changed. A British film version came out in 1940. The best-known version is MGM's Gaslight, released in May 1944, directed by George Cukor and starring Ingrid Bergman, Charles Boyer and Joseph Cotten, with Angela Lansbury in her film debut. Bergman won the Academy Award for Best Actress for the role.

Over the following decades "to gaslight" moved into everyday language, then into clinical and academic writing. In 2019 sociologist Paige Sweet published "The Sociology of Gaslighting" in the American Sociological Review, based on interviews with women in domestic violence support groups. She argued that gaslighting is rooted in social inequalities and power-laden intimate relationships, and that abusers often use gender stereotypes, for example that women are "irrational" or "hysterical," to make their version of events more believable to the victim and to others.

Gaslighting examples and common phrases

The Hotline groups gaslighting techniques into five types. The phrases below are typical examples; any of them can be innocent once, but a steady stream of them is a warning sign.

Technique	What it looks like	Example phrases
Withholding	Pretends not to understand or refuses to listen	"I'm not having this conversation again." "You're trying to confuse me."
Countering	Questions your memory even when you remember correctly	"That's not what happened." "You never remember things right."
Blocking or diverting	Changes the subject or attacks the source of your thoughts	"Did your sister put that idea in your head?" "You're imagining things."
Trivializing	Makes your needs or feelings seem unimportant	"You're way too sensitive." "You're getting upset over nothing."
Forgetting or denial	Pretends to forget events or denies promises	"I never said that." "You're making things up again."

Other phrases that often appear in gaslighting:

• "You're crazy. That never happened."
• "Are you sure? You have a terrible memory."
• "It's all in your head."
• "Everyone agrees with me; you're the only one who sees it that way."
• "I was joking. You can't take a joke."
• "You're overreacting, as usual."
• "If you really loved me you wouldn't accuse me of that."
• "You need help." (said to shut down a reasonable concern, not out of care)

A worked example

Maya notices $400 missing from the joint account. Her partner says she must have spent it and forgotten. She checks the statement and shows him a transfer to his personal account. He says the bank made an error, then that she agreed to it last week, then that she is "always paranoid about money" and this is why he cannot talk to her. By the end, the conversation is about her anxiety, not the transfer. She apologizes for "starting a fight." One episode like this is a bad argument. When it is the normal way problems end, it is gaslighting, and the money issue is also financial abuse.

Signs you are being gaslit

Psychoanalyst Robin Stern, author of The Gaslight Effect, has listed signs that someone may be on the receiving end, and the Hotline uses a version of her list. Ask yourself whether you:

• Constantly second-guess yourself.
• Ask yourself many times a day whether you are "too sensitive."
• Often feel confused or even "crazy" in the relationship.
• Are always apologizing.
• Cannot understand why you are not happier when much of your life looks good.
• Make excuses for the other person's behavior to friends and family.
• Hold back information from friends and family so you do not have to explain.
• Know something is wrong but cannot put it into words, even to yourself.
• Have started lying to avoid put-downs and twisted versions of events.
• Have trouble making simple decisions.
• Feel you used to be more confident, relaxed and fun.
• Feel hopeless, joyless or like you cannot do anything right.

A simple test: do you feel the need to record conversations or save texts just to prove to yourself that something happened? That impulse is itself a sign your perception is being undermined.

Gaslighting or an honest disagreement?

Normal disagreement	Gaslighting
"I remember it differently. Let's check."	"That never happened. You're making it up."
Both people can be wrong sometimes	You are always the one who misremembers
Focus stays on the issue	Focus shifts to your memory, emotions or mental health
Evidence settles it	Evidence is dismissed, or the story changes
You leave the conversation clear, even if annoyed	You leave confused and apologizing
Rare and specific	Repeated, building over months

Gaslighting in relationships

Gaslighting in romantic relationships rarely starts on day one. The Hotline notes it usually happens very gradually and may seem harmless at first. It often follows an intense early phase of attention, described in our guide to love bombing, which builds the trust that later makes the denials believable. Over time, the Hotline says, victims can become confused, anxious, isolated and depressed, and begin relying on the abusive partner to define reality.

Gaslighting often travels with other controlling behaviors: monitoring your phone, criticizing your friends, controlling money, or threatening to leave or to harm themselves when you raise concerns. The Hotline treats gaslighting as emotional abuse within a wider pattern of power and control, and its advocates help people experiencing it whether or not there has ever been physical violence. The confusion and on-and-off warmth can create a powerful attachment that is hard to break; see our guide to trauma bonds.

Gaslighting and narcissism

Gaslighting is strongly associated with narcissistic personality traits in popular writing, and it fits the narcissistic need to protect a fragile self-image and avoid blame. But gaslighting is a behavior, not a diagnosis, and people without any personality disorder can gaslight. A common related pattern is DARVO, a term from psychologist Jennifer Freyd: when confronted, the person Denies, Attacks, and Reverses the roles of Victim and Offender. For the quieter, harder-to-spot form of narcissism, read our guide to the covert narcissist.

Gaslighting by parents

Children are especially vulnerable to gaslighting because they rely on adults to explain reality. Parental gaslighting can sound like "That never happened," "You were a happy child, stop making things up," "I only yell because you make me," or denying that a parent's drinking, rage or neglect ever occurred. Children in these homes often learn to distrust their own feelings and to watch adults' moods closely, a pattern that can later show up as codependency. As adults they may feel destabilized after family visits or find that any attempt to talk about the past is rewritten on the spot. Therapy can help you build your own account of your childhood without needing your parent to agree with it.

Gaslighting at work

Workplace gaslighting can come from a manager or colleague who denies giving instructions, changes deadlines and then blames you for missing them, takes credit and insists the idea was theirs, or tells you that you are "too emotional" or "not a team player" when you raise a legitimate concern. Protect yourself by:

• Following up verbal conversations with a short email: "To confirm what we agreed today..."
• Keeping your own dated notes and copies of key documents outside of systems you could lose access to.
• Asking for instructions and feedback in writing.
• Talking to HR, a union representative or an employment attorney if the behavior is linked to discrimination, harassment or retaliation.

Medical gaslighting

"Medical gaslighting" is a newer, informal term for when patients feel their symptoms are repeatedly dismissed or attributed to stress, weight or anxiety without proper evaluation. A 2026 perspective paper in the Journal of General Internal Medicine proposed defining it as the repeated dismissal and invalidation of a person's health concerns by medical professionals, health care organizations or the wider medical system, leading the person to doubt the legitimacy of their concerns. The authors also warned that the term is sometimes stretched to cover ordinary communication breakdowns or unmet expectations.

Practical steps if you feel dismissed:

1. Write down your symptoms, when they started, what makes them better or worse, and how they affect daily life, and bring the list.
2. Ask directly: "What else could this be?" and "What would make you want to test for it?"
3. If a test or referral is declined, ask that the request and the reason be noted in your chart.
4. Bring a trusted person to appointments to listen and take notes.
5. Seek a second opinion if symptoms persist or worsen.

Never wait on symptoms that could be an emergency, such as chest pain, sudden weakness, trouble breathing or severe bleeding: call 911.

Why gaslighting works

• Trust. We naturally believe people close to us, especially partners, parents and authority figures.
• Gradual escalation. Small denials come first, so each new one feels only slightly worse than the last.
• Confidence. A calm, certain tone can override your own memory, especially when you are tired or stressed.
• Isolation. With fewer people around you, there is no one to say "I saw it too."
• Intermittent kindness. Warm periods make it easier to believe the bad moments were your fault or not as bad as you remember.
• Stereotypes. As Sweet's research describes, abusers can draw on stereotypes about women, mental illness, immigrants or other groups to make their story more credible.

How to respond to gaslighting

1. Do not try to win the argument. Someone who benefits from your confusion will not be persuaded by evidence. Debating the facts again and again keeps you inside their frame.
2. Use short, firm statements. "I know what I saw." "We remember this differently, and I'm not going to argue about my memory." "I'm going to end this conversation now."
3. Keep a private record. Note dates, what was said and what happened, in a place the other person cannot access. This is for you, to reset your confidence.
4. Check reality with someone you trust. A friend, relative or therapist outside the relationship can tell you whether your reactions make sense.
5. Watch for safety issues. If confronting the person has led to threats, intimidation or violence, talk to a Hotline advocate before taking further steps, and call 911 in an emergency.
6. Decide what you need. Some people choose couples counseling, though domestic violence experts generally caution against couples counseling when there is abuse. Others create distance or leave.

Recovering from gaslighting

Recovery is mostly about rebuilding trust in your own mind. Helpful steps include reconnecting with people you drifted away from, reading back over your notes to see the pattern clearly, practicing small decisions without asking for approval, and noticing when you start pre-apologizing. Many people find it useful to work with a therapist who understands emotional abuse; anxiety, low mood, poor sleep and constant self-doubt are common after long-term gaslighting and respond to treatment. Expect some days of doubt even after leaving. That is a lingering effect of the manipulation, not proof that you imagined it.
