Sometimes awakening in the morning interrupts bright dreams. A person opened his eyes and saw the real world, but the recent dream was clearly printed in memories, until the smallest details of the plot. And sometimes in the morning, you can remember anything. Popsci.com information portal said why people don't always remember their dreams.

The fact that you don't remember the content in your dream doesn't mean you don't dream about anything. Scientific works show that most people often see dreams – even those who claim that they never dream about anything. If you take these people, put them in the lab, wake them in the middle of the active sleeping stage and ask them what they think, they are guaranteed to remember something. The exception is only those who have lost the ability to see dreams of principles that are due to brain damage or diseases in specific areas.

In other words, dreams are a relative constant. The only problem is in the ability to remember them. There is no scientific confirmation here, because we still don't know much about sleep mechanism. However, there are some hypotheses.

First of all, memories for short dreams. Sleep studies show that a person is very difficult to remember a dream if he doesn't wake up in the course or right after him. We remember better dreams when we try to understand them in a state of consciousness – otherwise they will quickly disappear. It is likely that the difference in the activity of neurotransmitters, expression during sleep, is guilty. Awakening at night is related to the ability to memorize the dream increasing – many people often wake up for a few seconds to change posture. However, after a certain line, regular awakening at night can reduce the quality of sleep.

But to wake up correctly is only one of the good memory. The method and time of awakening, the stages of sleep and alarm clock also play an important role.

For the context, the sleeping process is divided into four stages: the fast sleeping stage (REM) and the three types not fast (nrem), repeated in the cycle throughout the night. NREM 1 is the easiest stage and the first stage in which one fails; It only lasted a few minutes. Then, in NREM 2, brain waves slow down and electrical activity occurs in short flash. Nearly half of an adult fall at this stage. From there, the brain moves to NREM 3, or in Rem.

NREM 3 – Deep dream. Brain waves are slower and still more stable. This type of sleep occurs relatively early at night, but it is very important for good sleep quality and about a quarter of the whole sleep time. Finally, in Rem, neurological activity is similar to a awake brain – the eyes of a person who does not move quickly under the eyelids.

Many people probably heard that the dreams came exactly at the remix. Indeed, often the longest and longest dreams appeared at the time. But in fact, dreams may dream at any stage of sleep, and sometimes those who are asked to talk about saturated dreams, the plot of even after waking up from other stages. It is just the percentage of their appearance is the highest in Rem.

Another important factor is the time of the night. The closer to the usual awakening time, the more the brain works. For many people, the most memorable dreams occur in the morning, but wake up along the alarm clock that reduces the chance of remembering a dream. Partly due to the fact that the signals of the alarm clock can pull one person out of the deep sleep period, when the memory is not too working. Not to mention the ringtone can cause a strong dance in the blood in the blood and immediately attract a person to pay attention to the upcoming issues that do not allow to wake up slowly and think about any dream.

Other variables affect the ability to remember the dream less controlled. For example, the comparative content and intensity of dreams play a big role in why some dreams are remembered much brighter. The emotional moments are more likely to be imprinted in memories during waking up – and with similar dreams. In addition, people with more open nature and certain variants of the structure of the brain tend to remember clear dreams.

Dream research is a difficult task, because the scientific community does not have a guaranteed test or any real -time scan shows that a person is a dream. The researchers must rely on the testimony of the people themselves. However, experiments begin to show that dreams and memory are connected to each other.
