Gaslighting: how to recognise it and what to say
When you leave a conversation no longer sure what actually happened — and it keeps happening. Here are the signs of gaslighting, the phrases it often uses, and calm replies that help you stay grounded.
Short answer
Gaslighting is a form of psychological manipulation in which a person is repeatedly made to doubt their own memory, perception and sanity. The gaslighter denies facts ("I never said that"), dismisses feelings ("You're overreacting") and rewrites events until the other person trusts their version of reality more than their own.
Where the term comes from
The word comes from the 1938 play Gas Light and the 1944 film Gaslight. A husband secretly dims the gas lamps in the house and, when his wife notices, insists she is imagining it. Little by little she stops believing her own eyes. Since then, "gaslighting" has described any tactic that undermines a person's trust in what they perceive.
8 warning signs of gaslighting
- Denying the obvious. You are told a conversation, promise or event never happened, even though you remember it clearly.
- Dismissing feelings. "You're too sensitive", "You're making a big deal out of nothing" — instead of discussing the issue.
- Rewriting history. Events shift a little every time they are retold, and you always end up at fault.
- Questioning your memory or sanity. "Your memory is terrible", "You need help".
- Shifting the blame. Every concern you raise ends with you apologising.
- Isolation. "Your friends think you're difficult too", "No one else would put up with you".
- Hot and cold. Sudden warmth after a harsh conversation that makes you wonder whether it was really that bad.
- How you feel. You are increasingly confused, second-guess yourself, apologise often and prepare for conversations as if for an exam.
Common gaslighting phrases and what is behind them
| Phrase | What is happening |
|---|---|
| "I never said that. You're making things up." | Your experience is denied instead of the facts being discussed. |
| "You're too emotional, it's impossible to talk to you." | The topic is replaced with a judgement of your reaction. |
| "You imagined it, nothing happened." | Your perception is called into question. |
| "You're twisting everything again." | You are made responsible for the confusion the other side creates. |
| "Everyone agrees that you're the problem." | Pressure from an imagined majority; isolation. |
| "You know your memory is bad." | Undermining your self-trust is used as an argument. |
Gaslighting or just different memories?
People genuinely remember things differently, and not every "I didn't say that" is manipulation. To tell them apart, look at four things:
- Repetition. One argument is a conflict. Gaslighting is a pattern that repeats over weeks and months.
- Willingness to check. An honest person agrees to look at the messages or clarify. A gaslighter dismisses the very idea of checking.
- Who ends up at fault. After every conversation, you are the one who is wrong and "unreasonable".
- How you feel. Constant confusion and fear of getting things wrong are an important signal, even if you can't explain exactly what is off.
How to respond to gaslighting: 6 calm steps
- Don't try to win the argument about memory. Gaslighting feeds on you proving your point while the other person denies it. Your goal is to keep your position, not to convince.
- Rely on your experience. "I remember it differently. We may see it differently, but my experience is real too."
- Return to facts. "Let's get back to specifics: we agreed on Friday, and it's in the messages."
- Name the process, not the person. "I notice that every time I talk about my feelings, the conversation turns to how sensitive I am."
- Write down what matters. Record agreements, keep messages, make notes after hard conversations. Not for a court case — for your own clarity.
- Leave conversations that go in circles. "I'm not willing to continue in this tone. Let's come back to it later."
Example conversations
In a relationship
- The other person
- "I never said that. You're making things up."
- What OPORA may notice
- Possible denial of the other person's experience. A single phrase is not enough to call it systematic gaslighting.
- A possible reply
- "I remember our conversation differently. Let's go back to the specific facts."
At work
- Manager
- "I never set that deadline. You must not have been listening in the meeting."
- A possible reply
- "I want us to understand the task the same way. I'll post a short summary of what we agreed in the chat so the dates are on record."
In the family
- Relative
- "Nobody hurt you, you were always too sensitive."
- A possible reply
- "You may see it differently, but it hurt me then. I'm talking about my feelings, not about who is right."
What not to do
- Spend hours proving your version of events — it is exhausting and only feeds the cycle.
- Answer accusations with accusations: the conversation quickly escalates.
- Keep your doubts to yourself. Talk to someone you trust — an outside view helps restore clarity.
How OPORA helps during the conversation
The hardest part of gaslighting is noticing it while it is happening. Later, alone, everything seems obvious, but in the moment the words disappear. OPORA is an AI assistant for difficult conversations that works in exactly that moment:
- it transcribes speech in real time, in English or Ukrainian;
- it flags phrases that resemble gaslighting, minimisation or blame shifting and explains what may be happening;
- it rates the risk as low, medium or high — as a hint, not a verdict;
- it suggests a calm reply that brings the conversation back to facts;
- it keeps sessions in your private account so you can later see whether the pattern repeats. Any session can be permanently deleted.
If you record a conversation with another person, let them know: it is fairer, and in many situations the law requires it.

When to get professional help
If gaslighting goes on for a long time or comes with control, threats, financial pressure or physical violence, it is no longer about finding the right words. Talk to a therapist or counsellor, or contact a local domestic abuse hotline. If you are in danger, call your local emergency number.
Frequently asked questions
What is gaslighting in simple terms?
Gaslighting is psychological manipulation in which someone repeatedly persuades you that you remember, perceive or judge events wrongly. The goal is for you to stop trusting yourself and rely on their version of reality instead.
How do I know if I am being gaslighted?
Warning signs: obvious facts are denied, your feelings are called overreactions, and after conversations you feel confused and keep apologising without knowing why. Repetition matters: a single disagreement about what happened is not gaslighting.
What should I say to a gaslighter?
Don't try to prove who is right; calmly hold on to your experience: "I remember it differently, and my experience matters too." Bring the conversation back to specific facts, write important agreements down, and leave arguments that go in circles.
Can gaslighting be unintentional?
Yes. People sometimes deny uncomfortable facts out of shame or defensiveness without planning to manipulate. The effect on you can be similar, so it is worth keeping your boundaries whatever the other person intends.
