Dreams Dreams are defined as images or stories that the mind creates at any time during sleep, but most real dreams occur during deep sleep, when the brain is at the peak of its activity, [1] where this period is known as REM. Rapid Eye Sleep), which is more concentrated in the second half of the night. [2] Sleeping stages Feeling sleepy due to the accumulation of natural adenosine in it during daylight hours, which leads to low blood pressure, slowed pulse and breathing, and muscle relaxation in all Throughout the body. [3] The rapid eye movement stage during sleep The brain moves through five different stages, including the rapid eye movement stage, which occurs after about ninety minutes of sleep, and continues for ten minutes or more, as this stage repeats several times during the night and increases Gradually every time, during this stage the brain and body go through several changes, including: Increased speed of eye movement, rapid and irregular breathing, increased blood pressure, heart rate, change in body temperature, and the brain is at the height of its activity as if the person was awake, and temporary paralysis of the extremities and face occurs. [4] How dreams occur during The rapid eye movement phase, the entire brain becomes at the height of its activity, and at this stage a network activation system that passes in circles from the brain stem to the thalamus and then to the cortex is controlled. The limbic system in the middle of the brain is responsible for dealing with emotions in general during dreams, and this system includes the amygdala, usually associated with emotions of fear that are activated during dreams. 5] The cerebral cortex is responsible for the content of dreams; Like seeing people, flying experience, etc., the visual cortex in the back of the brain is active, while parts of the frontal lobe are less active, which explains why people during dreams cannot distinguish, and accept dream events as if they were real, [5] After that, the brain interprets and analyzes these activities and creates a meaning for the random signals that produce the dream.
