Quizplus · Accepted Answer

John's experience of not feeling refreshed despite sleeping the whole night suggests he might be suffering from a type of dyssomnia, which includes disorders that cause difficulty initiating or maintaining sleep, or that involve excessive sleepiness. This category encompasses conditions that affect the amount, quality, and timing of sleep, unlike parasomnias, which involve abnormal movements, behaviors, emotions, perceptions, or dreams that occur while falling asleep, sleeping, between sleep stages, or during arousal from sleep.
