Interpretation of dreams-I dreamed that several duck eggs were found in my friend's chicken and duck nest.

Dreaming is a normal physiological phenomenon during sleep. Everyone has dreams, but there are many, few; Some wake up with fresh memories, others are vague or hard to detect. Those who claim that they never dreamed just forget. Therefore, there is no need to make a fuss about dreaming. Of course, if you dream more, it will affect your normal sleep. After waking up, my mind will be groggy, my spirit will be in a trance, my whole body will be exhausted, and my dreams will haunt me for a long time. This is pathological and harmful to the body.

There are different opinions about how dreams are formed. Pavlov's higher nervous activity theory holds that dreaming is the product of heterogeneous stages of sleep. In parasomnia's state, due to the increase of cerebral cortex blood flow and oxygen consumption, brain nerve cells are still in very active metabolic activities, and the inhibition state is not deep, and they are still in the so-called "working" (excited) state. Under the condition of receiving all kinds of internal and external stimuli, the corresponding memory traces will be revived, and then various dreams will be produced.
