MenuFearless doesnt mean you're completely unafriad and it doesnt mean you're bulletproof, it means you have alot of fears.. Dreams continue to perplex scientists, and sleepers alike, but recent research is shedding light on why we dream and even ways to control dreams.
When your head hits the pillow, for many it's lights out for the conscious part of you. In the study 264 university students rated how often they experienced nightmares on a scale from 0 to 4, never to always, respectively. That level of control may also help gamers turn a bloodcurdling nightmare into a carefree dream, she found in a 2008 study.
Scientists have long wondered why we dream, with answers ranging from Sigmund Freud's idea that dreams fulfill our wishes to the speculation that these wistful journeys are just a side effect of rapid-eye-movement (REM) sleep.
Her research revealed that our slumbering hours may help us solve puzzles that have plagued us during daylight hours.
So while dreams may have originally evolved for another purpose, they have likely been refined over time for multiple tasks, including helping the brain reboot and helping us solve problems, she said. While some researchers believe dreams are merely a quirk of sleep, others think they help you save memories, solve problems, and manage emotions. Some dreams seem pretty straightforward, showing how you feel about someone or how stressed you are. For the most part, dreams are similar for people from the same culture, but there are variations. While snoozing, you cycle between two basic states: REM (rapid eye movement) and non-REM sleep.

But the cells firing in your brain are very much awake, sparking enough energy to produce the sometimes vivid and sometimes downright haunted dreams that take place during the rapid-eye-movement stage of your sleep.
Such violent dreams may be an early sign of brain disorders down the line, including Parkinson's disease and dementia, according to research published online July 28, 2010, in the journal Neurology.
Research published in 2011 in the journal Sleep and Biological Rhythms, revealed that night owls are more likely than their early-bird counterparts to experience nightmares. And comparing notes in the morning may not be a turn-on for either guys or gals, as women are more likely to have experienced nightmares, suggests doctoral research reported in 2009 by psychologist Jennie Parker of the University of the West of England. This ability could help war veterans suffering from post-traumatic stress disorder (PTSD), Gackenbach reasoned. Turns out, at least part of the reason may be critical thinking, suggests Harvard psychologist Deirdre Barrett who presented her theory in 2010 at the Association for Psychological Science meeting in Boston. The visual and often illogical aspects of dreams make them perfect for the out-of-the-box thinking that is necessary to solve some problems, she speculates.
It's unclear, though, if women are just better at recalling their dreams than men or if they, in fact, have more nightmares. People who go blind in early childhood are also unlikely to have much visual imagery in their dreams. Dreams happen during both of these states, but sleep studies show that people have more brain activity, and more vivid dreams, during REM periods.
But as scientists are able to probe deeper into our minds, they are finding some of those answers. The results suggest the incipient stages of these neurodegenerative disorders might begin decades before a person, or doctor, knows it.

Both represent alternate realities, said Jayne Gackenbach, a psychologist at Grant MacEwan University in Canada. Jeanna has an English degree from Salisbury University, a Master's degree in biogeochemistry and environmental sciences from the University of Maryland, and a science journalism degree from New York University. If nothing comes to mind, it's possible you'll remember your dream later on, out of the blue.
Among their ideas is the stress hormone cortisol, which peaks in the morning right before we wake up, a time when people are more prone to be in REM, or dream, sleep. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. If you’re still sleeping at that time, the cortisol rise could trigger vivid dreams or nightmares, the researchers speculate. The reason may be a connection between the sense of smell and parts of the brain linked to dreaming.
