The truth about dreams

Certainly many times you have questioned why we dreamed, why someone always has nightmares while others are the opposite, what do they mean? Like sleep, dreams are considered a mysterious phenomenon. Here are interesting things related to 'dreamland' that you may not know.

>>>The truth behind your dreams

1. Violent dreams can be a warning sign

REM sleep disorder syndrome is a rare type of sleep disorder that makes people sometimes have violent acts such as punching, kicking and screaming while sleeping. Dreams like this can be an early sign of brain disorders, including paralysis and dementia.

Results from a 2010 study in the Neurology magazine show that the early stages of disorders that adversely affect neural tissue may appear decades before doctors discover it.

2. People who stay up late will often have nightmares

Staying up late helps you have more time to work but it also means you have to forget the beautiful, happy dreams.

The study was published in 2011 in the journal Sleep and Biological Rhythms, revealing that people who stay up at night will have many 'opportunities' to experience nightmares.

The dream is considered a mysterious phenomenon.

One of the possible reasons is because cortisol levels - also known as stress hormones - peak in the morning just before we wake up, during REM sleep. If you still sleep at the time, an increase in cortisol may cause haunting dreams, scientists speculate.

3. Men often dream about sex

This is the result of a 2009 study by psychologist Jennie Parker of the University of West of England.

In addition, Parker also found that women often experience more nightmares than men. These nightmares can be divided into three categories: fearful dreams (hunted or threatened); dreams related to the loss of loved ones; or messy dreams.

4. You can control your dreams

In a lucid dream (the dream in which the dreamer knows that he is dreaming), you have complete control of your role or control your imaginary experiences within that dream. If you are interested in dreams like this, do not ignore video games, Jayne Gackenbach, a psychologist from Grant MacEwan University (Canada) said.

'Gamers have the ability to control the virtual world in games and this can be applied to their dreams , ' Gackenbach said.

Conducting a series of analyzes, Gackenbach found that people who regularly play video games are more likely to experience lucid dreams by experiencing what happens outside of their bodies in the virtual world. Controlling dreams is similar to controlling game characters.

This finding contributes significantly to the treatment of post-traumatic stress disorder (PTSD) common in veterans, Gackenbach added.

5. Why do we dream

This is a question that challenges scientists long ago with various explanations.

Research by Harvard psychologist Deirdre Barrett of Harvard University revealed that the period of fast asleep can help us solve difficult problems, difficulties that appear during the day. The dream is a part of real life, it is not only a reflection of thinking simply but also contributes to the orientation and operation of the mind, Barrett said at the Psychological Association meeting that took place. end of May 2010.

So over time, they can carry two tasks: helping the brain to restart and solve problems, she said.
