Sleep cycles through the night, with deep sleep early on and more REM toward morning. Sleep proceeds in cycles of REM and NREM, the order normally being N1 → N2 → N3 → N2 → REM. There is a greater amount of deep sleep (stage N3) early in the night, while the proportion of REM sleep increases later in the night and just before natural awakening.

Interpretation of the Quotations
Sleep is better than medicine. --Proverb
Stages of Sleep
In mammals and birds, sleep is divided into two broad types: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM or nonREM) sleep. Each type has a distinct set of associated physiological, neurological, and psychological features. The American Academy of Sleep Medicine (AASM) further divides NREM into three stages: N1, N2, and N3, the last of which is also called delta, or slow-wave, sleep (SWS).
When one refrains from having a big supper, enjoys a good night’s sleep, and wakes up to a beautiful morning, he/she will feel like a hero. But if the same person eats too much in the evening, not sleeping well throughout the night, and wakes up to a rainy morning, he/she may suffer from a lack of confidence.
A dream reflects what you really feel in your subconscious world.

Quotations
A light supper, a good night’s sleep, and a fine morning have often made a hero of the same man who, by indigestion, a restless night, and a rainy morning, would have proved a coward. --Lord Chesterfield
Good health relies more on a good night’s sleep than on medicine.
Interpretation of the Quotations
A dream is a wish your heart makes, when you’re fast asleep. --Disney World advertisement
According to the United States Department of Health and Human Services in the year 2007, approximately 64 million Americans regularly suffer from insomnia each year. Insomnia is 1.4 times more common in women than in men.
Insomnia
Insomnia is a symptom of any of several sleep disorders, characterized by persistent difficulty falling asleep or staying asleep despite the opportunity. Insomnia is a symptom, not a stand-alone diagnosis or a disease. By definition, insomnia is "difficulty initiating or maintaining sleep, or both" and it may be due to inadequate quality or quantity of sleep. It is typically followed by functional impairment while awake. Both organic and non-organic insomnia without other cause constitute a sleep disorder, primary insomnia.
