We generally believe that if a person is over-eating or suffering from indigestion, he has nightmares, but research in Switzerland has termed nightmares useful.
Nervisologists at the University of Geneva, Switzerland, after researching more than 100 volunteers, said that those who have nightmares are better prepared to face real-world problems in the coming days. ۔
During this study, during the first phase, the activity of sleep was studied in the brain of 18 volunteers with the help of sensitive EEG (Brain Activity Measurement Tool). It turned out that the two cerebral areas called the “insula” and the “cingulate cortex” were also reacting to the feeling of fear and activities were increasing.
The role of the “amygdala” in the control of emotions, emotions, and fears is already known, but this was the first time that activity of two further parts was also revealed below.
As the nervous pressure / stress increases during wakefulness, the activity in ‘insula’ increases while it is also active in analyzing emotions. The ‘cingulate cortex’, on the other hand, also prepares us to face physical threats while awake.
During the nightmares these two parts were active, which showed that the dreamer was not only witnessing negative emotions and emotions, but also in real life, he was faced with “rehearsal”. ‘ doing.
In the next phase, another similar study was performed on 89 volunteers, using their MRI machine to test their brain activity. Volunteers were asked to write a regular diary of their dreams for the entire week. They were then awakened to an MRI machine and awakened to brain reactions by showing some scary pictures.
People who had nightmares more during this week, seeing horror images had less activity in their amygdala, insula, and cingulate cortex, indicating that they were experiencing mental and neurological fears. Ready to do.
On the contrary, volunteers who had never dreamed (or had never dreamed of the whole night) during the entire week had seen a lot of activity in the aforementioned terrifying images.
That is, they were not only frightened at seeing these pictures, but their nerves began to form at the same time to protect themselves from the feeling of fear.
Relationships between dreams and real life remain a defining reality in psychology and neurology today. However, our progress in this field is very slow because the brain is the most complex organ of the human body that we have not fully understood to date.
Details of this research have been published online in the latest issue of the research journal “Human Brain Mapping”.
