Warnings From Sleep: Nightmares and Protecting The Self. “All of this is evidence that the mind, although asleep, is constantly concerned about the safety and integrity of the self.”
Rosalind Cartwright — also known as the Queen of Dreams — is a leading sleep researcher. In The Twenty-four Hour Mind: The Role of Sleep and Dreaming in Our Emotional Lives, she explores the role of nightmares and how we use sleep to protect ourselves. When our time awake is frightening or remains unpressed, the sleeping brain “may process horrible images with enough raw fear attached to awaken a sleeper with a horrendous nightmare.” The Science of Sleep: Regulating Emotions and the Twenty-four Hour Mind. “Memory is never a precise duplicate of the original; instead, it is a continuing act of creation.”
Rosalind Cartwright is one of the leading sleep researchers in the world. Her unofficial title is Queen of Dreams.

Melatonin. Why Six Hours Of Sleep Is As Bad As None At All. Not getting enough sleep is detrimental to both your health and productivity.
Yawn. We've heard it all before. But results from one study impress just how bad a cumulative lack of sleep can be on performance. Subjects in a lab-based sleep study who were allowed to get only six hours of sleep a night for two weeks straight functioned as poorly as those who were forced to stay awake for two days straight. The kicker is the people who slept six hours per night thought they were doing just fine. This sleep deprivation study, published in the journal Sleep, took 48 adults and restricted their sleep to a maximum of four, six, or eight hours a night for two weeks; one unlucky subset was deprived of sleep for three days straight. Why broken sleep is a golden time for creativity — A... It is 4.18am.

Hypnagogia is the imagery, sounds and strange bodily feelings that are felt at “sleep onset.”
This is a simplification though, as researchers have noted hypnagogic imagery in the lab at periods of quiet wakefulness as well as stage 1 sleep. Others have correlated hypnagogia with pre-sleep alpha waves and also REM intrusion into sleep onset. The truth is that the wake-sleep transition is still not understood. And neither are its trippy visuals. whispy lights, multi-dimentional geometric objects, or a sudden image like a stranger’s face Few people remember hypnagogic imagery. The Science of Lucid Dreaming. Brain Zaps Can Trigger Lucid Dreams. Lucid dreams, in which people are aware of and can control their dreams, are rare.
But now scientists have found they can induce this weird state of mind in people by zapping their brains with a specific frequency of electricity. "I never thought this would work," said study researcher Dr. John Allan Hobson, a psychiatrist and longtime sleep researcher at Harvard University.

Most people only think that there is one way to sleep: Go to sleep at night for 6-8 hours, wake up in the morning, stay awake for 16-18 hours and then repeat.

Smug early birds take note: Night owls actually have more mental stamina than those who awaken at the crack of dawn, according to new research.
"It's the late risers who have the advantage, and can outperform the early birds," said Philippe Peigneux, a professor of clinical neuropsychology at the Free University of Brussels in Belgium, who along with co-author Christina Schmidt published the counterintuitive findings in the latest issue of the journal Science . Using magnetic resonance imaging, the pair conducted an experiment that measured alertness and ability to concentrate in 30 subjects who were naturally "extreme" early or late risers. The early risers got up between 5 a.m. and 6 a.m., and the late risers at noon. Maintaining their natural schedules, the volunteers spent two consecutive nights in sleep labs. After 10 hours of being awake, the early birds showed reduced activity in brain areas linked to attention span, compared with the night owls. How to Spend the Last 10 Minutes of Your Day. How much sleep did you get last night?

Katherine Streeter for NPR While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers say. During sleep, the flow of cerebrospinal fluid in the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found. Night Owls Smarter: A New Study Suggests That Late-To-Bed-Late-To-Rise Leads To Greater Workplace Success : Healthy Living.
A new study suggests the early riser has only more time for mediocrity. Researchers at the University of Madrid followed nearly 1,000 teenagers and found that night owls bested "morning larks" in qualities linked to general intelligence, such as inductive reasoning, conceptual and analytical thinking. "What hath night to do with sleep? " asked John Milton, the 17th century English poet who worked as a civil servant, among a class of people generally obliged to rise early in the morning. Indeed, while many early risers outperform night owls in school, researchers said the late risers surpass their counterparts later in the workforce. Differences in preset circadian rhythms might explain the 8 percent advantage enjoyed by early risers in school, researchers said. A previous study conducted by the U.S. Jim Horne, a professor of psychophysiology at Loughborough University, commented on the Spanish study.
