What is Nightmares and night terrors in adults?
Nightmares are vivid, disturbing dreams that wake you feeling frightened or distressed, usually during the lighter, dream-heavy stages of sleep. Night terrors are different: they involve sudden episodes of intense fear, screaming, or thrashing during deep sleep, with little or no memory of them afterwards.
Both can be triggered by stress, anxiety, irregular sleep, alcohol, certain medications, or underlying mental health conditions such as PTSD. Occasional episodes are common, but frequent or distressing occurrences can affect sleep quality and daytime wellbeing.

- 2Manage stress before bed.Relaxation techniques, journaling, or winding down without screens can reduce the likelihood of disturbed sleep.
- 3Limit alcohol and late caffeine.Both can disrupt sleep architecture and increase the chance of nightmares or night terrors.

BarnMD Bottom Line
Occasional nightmares and night terrors are a normal part of sleep, but frequent or distressing episodes are worth discussing with a GP, especially if they're linked to stress or trauma.
Addressing the underlying stress, sleep habits, or trauma behind recurring episodes is usually more effective than treating the nightmares alone.
