Dreaming, which is beneficial for the recovery of brain function, provides a regular and beneficial stimulation of the nerves in the brain, allowing the central nervous system to adjust to a state of readiness to cope with the ever-changing external world. Dreaming, in turn, simulates the activity of the waking state and prevents the brain’s nerves from ceasing to function at night. Dreaming also allows the information in the brain to be re-cleaned. Moreover, protein synthesis in the brain cells is accelerated when dreaming. Thus, dreaming is important for the maturation of the nervous system in young children, for example, forming new synaptic connections, facilitating the development of memory, and perhaps being one of the foundations of personality development. As we can see, dreams are the result of the brain’s regulatory centers balancing various bodily functions, as well as being necessary for healthy brain development and the maintenance of normal thinking. If the regulating center of the brain is damaged, dreams cannot be formed. Long-term dreamlessness is a cause for alarm. Therefore, scientists believe that the average life expectancy of people who dream more during sleep is relatively longer than that of people who dream less.
