Overview

Night terrors and nightmares are common sleep disturbances, particularly in children, though adults can also experience them. They differ in when they occur during sleep and whether the event is remembered. Night terrors happen in the early part of the night, where a person may appear awake but is not, and has no memory of the event. Nightmares, however, are frightening dreams that occur later in the night, from which a person awakens and can often remember. These sleep events can be triggered by various factors, including being tired, stressed, or unwell, and sometimes by certain medications or underlying health conditions. While most cases improve on their own, understanding the triggers and implementing supportive strategies can help manage them. Management often involves establishing good sleep hygiene, addressing stress or anxiety, and in some cases, psychological therapies. It's important to distinguish between night terrors and nightmares, as the approach to helping someone experiencing them can differ.
