Gaslighting: what it is, examples, and how to respond
Gaslighting is a form of emotional abuse in which someone repeatedly denies, twists or dismisses what you saw, heard or felt until you start doubting your own memory, judgement or sanity. The name comes from the 1938 play Gas Light and its 1944 film, in which a husband secretly dims the gas lamps and insists his wife is imagining it. It is a description of behaviour, not a medical diagnosis. One argument where two people remember things differently is not gaslighting; a sustained pattern that leaves you confused, anxious and dependent is. Keeping notes and getting an outside view are the most useful first steps.

Gaslighting is manipulation that makes you doubt your own reality. The other person repeatedly denies things that happened, insists you said or did things you did not, dismisses your feelings as oversensitivity, or tells you your memory cannot be trusted — until you begin to question yourself instead of them. Over time it can leave a person anxious, confused, isolated and dependent on the very person who is misleading them.
It is a real and harmful pattern, often part of emotional or domestic abuse. It is also one of the most overused words on the internet. Both things are true, and this page tries to help you tell them apart.
Where the word comes from
The term comes from Patrick Hamilton's 1938 play Gas Light and the 1944 film Gaslight. A husband, trying to get hold of hidden jewels, secretly dims the gas lamps and makes noises in the attic, then tells his wife she is imagining it. He isolates her, moves her belongings and insists she is forgetful and unwell, until she starts to believe she is losing her mind. Psychologists and then the wider public took the title as a name for this kind of reality-bending control.
What gaslighting sounds like
Advocacy organisations describe a handful of recurring tactics. Any one of these can happen innocently once. What marks gaslighting is repetition, and a direction: it keeps pushing you towards self-doubt.
| Tactic | Example |
|---|---|
| Denying what happened | “I never said that.” “That didn't happen — you are making it up.” |
| Questioning your memory | “You always remember things wrong.” “You're getting forgetful, just like your mother.” |
| Trivialising your feelings | “You are too sensitive.” “Why do you make a big deal of everything?” |
| Diverting | “Who put that idea in your head? Your sister?” — and the topic becomes someone else |
| Withholding | Refusing to discuss it, pretending not to understand, or going silent for days |
| Rewriting the story | Blaming you for their outburst, until you are the one apologising |
How you might feel
- Constantly second-guessing yourself and your memory
- Apologising all the time, even when you are not sure what you did
- Confused or foggy after conversations with this person
- Making excuses for them to family and friends
- Feeling you cannot do anything right, or that you are “going mad”
- Being anxious, low or on edge at home — , low mood and are common results
Gaslighting or an ordinary disagreement?
Human memory is not a recording. Two honest people often remember the same event differently, and both can be partly wrong. Someone who says “I don't remember it that way” is not necessarily gaslighting you. Nor is an older relative with memory problems or early dementia who insists something never happened — that is illness, not manipulation, and it needs a doctor.
| Ordinary disagreement | Gaslighting |
|---|---|
| Happens now and then | A repeated pattern over months or years |
| Both people can say “maybe I'm wrong” | Only you are ever wrong |
| Evidence changes minds — a message or receipt settles it | Evidence is dismissed, or you are blamed for checking |
| You leave the argument annoyed but sure of yourself | You leave doubting your memory, judgement or sanity |
| Your relationships with others continue | You are gradually cut off from people who might back you up |
Where it happens
Marriage. Gaslighting is most often described between partners, where it tends to come with other controlling behaviour. A husband who hides money and then insists his wife is careless with it, or who denies promises about work, visits home or education, is using it to keep control.
Joint families. A daughter-in-law may be told repeatedly that the hurtful things said to her were never said, that she is “too sensitive”, or that “this happens in every house”. When several relatives repeat the same version, it is very hard to trust your own. Sometimes this is genuine misunderstanding across generations; sometimes it is a deliberate way to keep someone quiet.
Parents and children. A parent who routinely denies a child's experiences — “that never hurt you”, “you are imagining things” — can leave long-lasting self-doubt. This is different from a parent reasonably correcting a child's account.
Workplaces. A manager who denies instructions they gave, takes credit and then questions your competence, or tells colleagues you are unreliable, can gaslight at work. Written records matter most here.
How to respond
You do not need to prove the other person's motive. You only need to trust your own records and your own sense of what is happening.
- Keep a private record. Write down dates, what was said and what happened, soon after. Save messages and emails. Keep the record somewhere the other person cannot reach — not a shared phone.
- Get an outside view. Describe events to a trusted friend, sibling, doctor, counsellor or religious scholar who is not part of the conflict. Their reaction helps you recalibrate.
- Stop arguing about the past. You will not win a debate about what happened with someone who keeps changing it. Say “I remember it differently” and move on to what you need now.
- Protect your relationships. Stay in contact with family and friends, even briefly. Isolation is what lets gaslighting work.
- Look after your mind. If you are anxious, low or cannot sleep, see a doctor or . Gaslighting erodes , and rebuilding it is part of recovery.
Why it works so well
Gaslighting rarely starts with big lies. It usually begins with small contradictions from someone you love or depend on, at a time when you have reason to trust them. Several things make it effective:
- Trust. We are built to believe people close to us. Doubting a husband, parent or elder feels disloyal.
- Dependence. When someone controls the money, the home or your contact with family, disagreeing with their version of events feels risky.
- Stereotypes. A sociologist who studied gaslighting in abusive relationships found that abusers draw on existing stereotypes — for example, that women are “emotional” or “unstable” — to make their version more believable to the victim and to others.
- Exhaustion. After enough arguments, agreeing becomes the easiest way to get peace.
When it is part of domestic abuse
Gaslighting often sits alongside other abuse: controlling money, restricting where you go or who you see, checking your phone, threats, and physical or sexual violence. The World Health Organization counts psychological abuse and controlling behaviour as forms of intimate partner violence. If this describes your life, you are not overreacting, and it is not your fault.
When to get help
- You are frightened of the person, or they have threatened or hurt you or your children.
- You no longer trust your own memory or judgement about ordinary things.
- You feel low, anxious or hopeless most days, or have thoughts of harming yourself.
- Friends or family have told you that you have changed, or that they are worried.
Recovering afterwards
Even after the relationship ends or the situation improves, self-doubt can linger for a long time. People describe checking and re-checking their memory, apologising automatically, or struggling to make simple decisions. This is an understandable after-effect, not a permanent change in who you are. Rebuilding trust in your own judgement takes practice: making small decisions and seeing them turn out fine, spending time with people who take you seriously, and, if needed, working with a counsellor or psychologist. If low mood or anxiety persists for weeks, see a doctor — and anxiety after emotional abuse are common and treatable.
