Have you ever had nightmares? Read the story to find out why!

Researchers recently came to know areas of the brain responsible for dreams and nightmares. After tracing the brain activity of a group of people, the region that controls dreams and nightmares from the brain is the posterior cortical-hotzone. The difference in the dream plot and nature is due to the contribution of several parts of the brain's back area to the process of making dreams.

One of the researchers from the Center for Gender and Awareness at the University of Wisconsin-Madison, said that the back parts of the brain are active during a person's vision of a dream or nightmare, and the activation of these areas depends on the different dream contents that may include seeing a certain face or movement . Scientists have been able to monitor these specific areas by distinguishing the time when a person sees a dream or a nightmare from the time he enjoys a quiet sleep free of dreams and nightmares. The researchers found that the strength of the activity shown by these areas can be used as an indicator to distinguish any stage of sleep currently passes by the person and accuracy of 90%

It is worth mentioning that the sleeper goes through several stages, part of which is classified under the case of eye movement is not fast sleep, and another part is classified under the case of rapid eye movement. Researchers often associate dreams with a marked increase in brain activity in the rapid eye movement phase of sleep, while the absence of dreams and nightmares is usually associated with low-frequency activity in the brain during non-rapid eye movement during sleep. However, some studies have recorded cases where individuals were awakened during the passage of non-rapid eye movement and said they were dreaming, and cases where the exact opposite, was awakened individuals from the stage of rapid eye movement denied that they were dreaming.

The researchers said that these initial results were based on the examination of certain areas of the brain alone, because of the presence of certain areas in the brain is difficult to monitor their activity techniques they used. Researchers hope they can understand the area of the brain's back cortex from knowing how it is possible to create virtual human experiences that help them feel like they are in another world, both in a "parallel world" or in a world of abstract dreams. Manipulating the way in which we receive our senses and our awareness of reality.
