Quizplus · Accepted Answer

Sara's sudden cry and sitting up straight in bed is characteristic of a night terror, which is a type of sleep disorder. Night terrors typically occur during non-REM sleep and are often accompanied by intense fear or panic. The individual experiencing a night terror may be difficult to awaken and may have no memory of the episode afterwards. Sleep apnea, nightmares, and REM deprivation do not fit the description provided.
