11 Strange Things Narcissists Do That Most People Don’t Notice

Have you ever met someone whose behaviour was so strange that you struggled to explain it to anyone else?

Perhaps they copied everything about you when you first met, denied conversations you clearly remembered, or treated complete strangers better than the people closest to them.

Maybe they seemed charming, generous and confident in public, but behind closed doors, they were secretive, jealous, controlling or unnecessarily cruel.

One of the most confusing things about narcissistic behaviour is that it doesn’t always make sense to the person experiencing it.

And when you try to explain what’s happening, other people might struggle to believe you because they’ve experienced a completely different side of that person.

Although these behaviours aren’t exclusive to narcissism, certain patterns can appear in relationships involving people with strong narcissistic traits.

If you’re ready to stop overthinking, calm your nervous system, and finally break the trauma bond, my structured CBT-based recovery programme gives you the practical tools to rebuild confidence and regain control. 👉 Click here to start your healing journey:

Here are 11 strange behaviours worth recognising.

1. Mirroring Your Personality

Have you ever met someone who seemed to have absolutely everything in common with you?

They loved the same music, shared your interests, agreed with your opinions and appeared to want exactly the same future.

It felt like you’d finally met someone who understood you.

Mirroring can be a normal part of building connections. However, when used manipulatively, someone may deliberately reflect your interests, values and personality to create a false sense of compatibility.

You think you’ve found someone who understands you, but they may simply be showing you what they know you want to see.

2. Gaslighting You About Things That Happened

One of the most damaging behaviours associated with emotional manipulation is gaslighting.

You remember a conversation clearly, but they insist it never happened.

You confront them about something they said, and they accuse you of imagining things.

You show them evidence, and somehow you’re still wrong.

Over time, repeated denial and distortion can make you question your memory, judgement and perception of reality.

Eventually, you stop asking whether they’re telling the truth and start wondering whether you can trust yourself.

3. Hoarding Possessions, Information or Resources

Some people with narcissistic traits become unusually possessive about things they believe give them security, status or control.

They might accumulate possessions, refuse to share resources or become extremely protective of information.

In relationships, this can also involve controlling access to money, important documents or shared belongings.

However, hoarding itself is not a defining symptom of narcissism and can have many unrelated causes.

The important warning sign is when possessions or resources are deliberately used to control another person.

If you’re ready to calm the constant alertness, regulate your triggers, and help your body move beyond survival mode, my step-by-step nervous system recovery programme gives you practical tools to feel calmer, safer and more in control after narcissistic abuse. 👉 Click here to start healing your nervous system:

4. Being Extremely Secretive

Have you ever been in a relationship where someone expected complete transparency from you while keeping large parts of their own life hidden?

They want to know where you’re going, who you’re speaking to and what you’re doing.

Yet they become defensive when you ask similar questions.

Their phone is private. Their whereabouts are vague. Their explanations constantly change.

They demand honesty while treating your reasonable questions as accusations.

Privacy is healthy. Secrecy becomes concerning when it accompanies repeated dishonesty, manipulation and unequal expectations.

5. Exhibitionism and Constant Attention-Seeking

Some narcissistic individuals appear to need constant attention.

They might exaggerate achievements, dominate conversations, boast about their appearance or deliberately create situations where everyone notices them.

They may turn ordinary events into opportunities to demonstrate their importance.

Even someone else’s celebration can become about them.

This behaviour can be associated with a strong need for admiration and external validation.

It’s not simply wanting attention. It’s when their need for attention consistently comes at everyone else’s expense.

6. Mocking and Belittling Other People

Have you ever noticed someone who constantly makes jokes at other people’s expense but becomes furious when anyone jokes about them?

They ridicule your appearance, intelligence, achievements or insecurities.

When you express hurt, they tell you you’re too sensitive.

They insist they’re only joking.

But there’s a difference between sharing a joke and repeatedly humiliating someone.

When the joke is always at your expense, and your feelings never matter, it stops being harmless humour.

Repeated belittling can gradually damage confidence and make someone afraid to express themselves.

7. Trying Desperately to Impress Strangers

This is one of the behaviours that can leave people closest to a narcissistic individual feeling particularly confused.

They might be dismissive, impatient or critical towards their partner or family.

Yet the moment someone unfamiliar enters the room, their personality appears to change.

Suddenly, they’re charming, generous, helpful and attentive.

They’ll go out of their way to impress someone they’ve just met while neglecting those who have supported them for years.

Sometimes, the people who know them the least receive the version of them that their loved ones have been begging to experience.

This contrast can make emotional abuse particularly difficult to explain.

8. Repeated or Compulsive Lying

Have you ever caught someone lying about something so insignificant that you couldn’t understand why they bothered?

Some people with narcissistic traits may lie to protect their image, avoid accountability, gain admiration or maintain control.

They might exaggerate achievements, invent stories, deny mistakes or completely rewrite events.

When confronted, they may create another lie to cover the first.

Not everyone who lies has narcissistic traits, and not everyone with narcissistic traits lies compulsively.

However, persistent dishonesty combined with blame-shifting can make a relationship emotionally exhausting.

You become so focused on establishing the truth that you lose sight of how unhealthy the situation has become.

9. Love Bombing at the Beginning of Relationships

Have you ever met someone who seemed completely obsessed with you almost immediately?

They constantly messaged, showered you with compliments and spoke about a future together before you’d really got to know each other.

You were their soulmate.

They’d never felt this way before.

Everything moved incredibly quickly.

Sometimes intense affection is genuine. But love bombing becomes concerning when excessive attention is used to accelerate emotional attachment, weaken boundaries or create dependency.

Once the relationship feels secure, that affection may disappear or become conditional.

The person who once made you feel like the centre of their universe may eventually make you feel as though you’re asking too much simply by wanting basic consideration.

10. Threatening and Intimidating Behaviour

Not all emotional abuse involves shouting or physical violence.

Intimidation can be subtle.

Someone might threaten to leave whenever you disagree, punish you with prolonged silence, threaten your reputation or imply there will be consequences if you don’t comply.

They may use their anger to make you afraid of expressing your needs.

Over time, you begin anticipating their reactions.

You carefully choose your words, avoid certain subjects and change your behaviour to prevent conflict.

You stop making decisions based on what you want and start making them based on what will keep them calm.

Threats, intimidation and coercive control are serious warning signs of abuse, regardless of whether someone has a personality disorder.

11. Being Envious of Other People’s Happiness

Have you ever shared good news with someone only to notice that they seemed irritated rather than pleased?

Perhaps they dismissed your achievement, changed the subject or immediately started talking about something they’d accomplished.

Some people with narcissistic traits struggle when someone else’s success challenges their sense of superiority.

Instead of celebrating you, they may minimise your achievements or turn everything into a competition.

You might eventually stop sharing your happiness because you know it will somehow become a problem.

A healthy relationship should make you feel supported in your success, not guilty for experiencing it.

Why Recognising These Behaviours Matters

The most important thing to understand is that one unusual behaviour doesn’t automatically mean someone is a narcissist.

What matters is the wider pattern.

Are they repeatedly dishonest? Do they undermine your confidence? Do they respect your boundaries? Can they accept responsibility when they’ve hurt you?

And perhaps most importantly, how do you feel about yourself when you’re around them?

If you’ve spent years questioning your judgement, apologising for things you didn’t do and trying to understand someone else’s behaviour, you may have developed beliefs about yourself that aren’t true.

You might believe you’re too sensitive, difficult to love or responsible for everyone else’s emotions.

But those beliefs can be challenged.
