Nightmares vs Night Terrors: What’s the Difference?
We have all had dreams we wish were real.
Winning the lottery. Meeting a celebrity. Living a perfect moment.
Then the alarm goes off.
And reality returns.
But not all dreams are pleasant.
Some dreams feel unsettling, intense, or even frightening.
You may wake up feeling anxious or uneasy.
So what is the difference between a bad dream, a nightmare, and a night terror?
Understanding these differences can help you make sense of your sleep.
😨 What are nightmares?
Nightmares are vivid, frightening dreams.
They often feel very real and can stay with you long after you wake up.
You are more likely to:
- Wake suddenly
- Feel anxious or scared
- Remember the dream clearly
- Experience physical symptoms like sweating or a racing heart
Nightmares usually happen during REM sleep.
This stage occurs more often in the later part of the night.
That is why nightmares often happen in the early morning hours.
Who gets nightmares?
Nightmares are common in both children and adults.
They affect around 25% of children aged 5 to 12.
But adults can experience them too.
Although they can feel intense, nightmares are usually not harmful.
You may simply need time to relax before falling back asleep.
😟 What are bad dreams?
Bad dreams are less intense than nightmares.
They may feel unpleasant, but they are not usually terrifying.
Key differences include:
- You are less likely to wake up
- The emotional response is milder
- Physical symptoms are rare
- The memory fades more quickly
You may still remember parts of the dream.
But it will not feel as overwhelming as a nightmare.
Bad dreams are very common.
Most people experience them from time to time.
😱 What are night terrors?
Night terrors are very different from nightmares.
They are more intense and more physical.
They can also be distressing to witness.
Night terrors are most common in children.
But they can continue into adulthood.
What happens during a night terror?
During a night terror, a person may:
- Sit up suddenly in bed
- Scream or shout
- Appear panicked or confused
- Sweat or breathe heavily
- Move suddenly or even sleepwalk
It can be difficult to wake someone during a night terror.
They may not respond or recognise you.
In some cases, they may not remember anything the next morning.
When do night terrors happen?
Unlike nightmares, night terrors occur during non-REM sleep.
This is usually earlier in the night.
🧠 What causes nightmares and night terrors?
The exact cause is not always clear.
However, several factors may increase the likelihood of disturbed dreams.
Common triggers include:
- Stress or anxiety
- Trauma or emotional upset
- Illness or fever
- Sleep deprivation
- Certain medications
- Alcohol or substance use
Night terrors are often linked to stressful life events.
These may include shock, grief, or major changes.
⚠️ Are night terrors dangerous?
Night terrors themselves are not harmful.
However, physical movement during an episode can increase risk.
In rare cases, a person may:
- Fall out of bed
- Walk into objects
- Hurt themselves accidentally
If night terrors are frequent, severe, or unsafe, it is important to seek medical advice.
