Night Terrors vs Nightmares
Understanding the difference and how to cope with both
Night terrors and nightmares are often confused, but they are fundamentally different experiences that occur during different sleep stages.
Nightmares happen during REM sleep, usually in the second half of the night. You can often remember them vividly upon waking, and they tell coherent (if frightening) stories.
Night terrors occur during deep non-REM sleep, typically in the first few hours. The sleeper may scream, thrash, or sit up with eyes open — but they're not truly awake and usually have no memory of the episode.
Nightmares are more common in adults and are often triggered by stress, anxiety, trauma, or certain medications. They can be worked with therapeutically through techniques like Image Rehearsal Therapy.
Night terrors are more common in children (ages 3-12) and most outgrow them. In adults, they may be linked to sleep deprivation, fever, or sleep disorders.
Recurring nightmares often carry important psychological messages. Rather than avoiding sleep, consider keeping a dream journal and exploring the themes with a therapist.
Both can be reduced by maintaining good sleep hygiene: consistent schedule, cool dark room, no screens before bed, and managing daytime stress.
