Dreams are known as images or stories that the mind creates at any time during the period of sleep, but most realistic dreams occur during deep sleep when the brain is at its peak activity, where this period is known as rapid eye movement ( REM), which are more concentrated in the second half of the night.
Sleep stages
Feeling sleepy
The body feels sleepy due to the accumulation of natural adenosine in it during daylight hours, which leads to a decrease in blood pressure, slowed pulse and breathing, and relaxation of muscles throughout the body.
Rapid eye movement stage
During sleep, the brain moves through five different stages, including the rapid eye movement phase, which occurs after about ninety minutes of sleep, and continues for ten minutes or more, since this phase repeats several times during the night and increases gradually each time, and during this phase, the brain passes And the body has several changes including; Increase in the speed of eye movement, rapid and irregular breathing, increased blood pressure, heart rate, and a change in body temperature and the brain is at its peak activity as if the person was awake, and temporary paralysis of the limbs and face occurs.
How dreams occur
During the REM phase, the entire brain becomes at its fullest, and at this stage, it is controlled by a retinal activation system that passes in circuits from the brainstem to the thalamus and then to the cortex. The limbic system or 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 the emotions of fear, which are active during dreams.
The cerebral cortex is responsible for a dream content. Such as seeing people, the experience of flying, etc., and the visual cortex in the back of the brain is active, while parts of the frontal lobe are less active, and this explains the inability of people during dreams to distinguish and to accept the events of dreams as if they were real.
Then the brain interprets and analyzes these activities and creates meaning for the random signals from which the dream is produced.

Some researchers believe that dreams are non-sensory activities without a goal or meaning that the brain conducts during the period of sleep, while others believe that they are necessary and important for the health of the body, mind, and emotion, and studies have shown that people who do not enter the stage of rapid eye movement, suffer from anxiety and depression And stress, difficulty concentrating, weight gain, hallucinations, and many researchers indicate that dreams help to solve problems, process emotions and merge memories, and Sigmund Freud believes that dreams are a window into the subconscious, a way to satisfy unacceptable desires in society.
