Why do people dream of nightmares?
Why do people dream of nightmares? |Dreams are seen by almost everyone and billions or billions of people often have nightmares or nightmares. And if you are one of them, the good news is that these nightmares can actually be a positive benefit. This claim came up in joint research by scientists from the US and Switzerland. Research from the University of Geneva, the University Hospital of Geneva, and the University of Wisconsin found that sleep depressions help control fear during sleep apnea. During this research, scientists examined how the brain reacts to different types of dreams, and what brain parts are activated during that time.
They discovered that nightmares improve the usefulness of the part of the brain that responds to frightening experiences during awakening.
But scientists also discovered that a nightmare that is too scary can have a negative effect. The results of this study were published in the journal Journal of Human Brain Mapping and for this purpose, brain stimulation was evaluated using EEG electrodes on the heads of volunteers.
The scientists applied 256 EEG electrodes to the heads of 18 volunteers and were awakened several times overnight. Each time you wake up, these volunteers receive answers to various questions such as did you dream? If yes, are you feeling scared? Etc. etc. According to the researchers, when analyzing mental movement, we identified that during the dream, the brain parts that stimulate emotions such as fear or fear. For the first time, we were able to identify the nervous parts of the brain during the dream, and found that such areas are triggered by fear during sleep and awareness, he said. Researchers then instructed 89 volunteers to write dreams in a diary for a week to examine the relationship between emotional distress during sleep and wakefulness. Each morning these volunteers were asked to dream and a week later an MRI machine was used. In this machine, people were shown emotionally manipulative images such as attacks or dangerous situations, and images of brain parts that were stimulated in fear.
Research has shown that nightmares prepare people to fight fear in the state of awareness, and the more nightmares they dream, the more the brain part that controls fear. According to researchers, dreams can potentially train us to respond to our future state of awakening and to be prepared to deal with real-life risks. However, if the intensity of the dream increases too much, it becomes negative rather than positive as it affects sleep, while the negative effect can be sustained even after awakening
