What distinguishes sleep terror from nightmares?

• A. Sleep terrors are associated with vivid dreams
• B. Sleep terrors occur during rapid eye movement sleep
• C. Sleep terrors can involve panic without dream recall
• D. Sleep terrors happen only during the day

Answer: (C)

Sleep terrors, also known as night terrors, are distinct from nightmares primarily because they can occur without any recollection of a dream. During an episode of sleep terror, which typically happens during non-REM sleep, a person may experience intense fear or panic and exhibit physical responses such as screaming, thrashing, or sweating. However, unlike nightmares that occur during REM sleep and are often remembered in detail upon awakening, individuals experiencing sleep terrors usually have no memory of the episode the next day. This characteristic of sleep terrors being recognized by the panic-like symptoms and lack of dream recall sets them apart from nightmares, where vivid dreams can be recalled and can often be disturbing or frightening. This distinction is important not only for accurate diagnosis but also for effective treatment strategies in sleep disorders. In contrast, the other options provided misstate the nature of sleep terrors or nightmares. For instance, sleep terrors do not occur during REM sleep; rather, they occur during deep, non-REM stages of sleep. Additionally, while sleep terrors are not confined to the daytime, they are often more repetitive and arise during specific stages of nighttime sleep. Understanding these differences is crucial for clinicians and caregivers in providing appropriate support and interventions for affected individuals.
