Why the incubation period without clinical symptoms of the disease, but dreams reflect the disease?From the perspective of the pathology of many physical and mental illness in the incubation period symptom is not obvious.Physiological psychologists believe that modern people or awake during the day, by stimulating signal of the outside world, the brain busy at the beginning of a disease information.In addition, the brain can be adjust to this, and make it disappear.And when the people in the sleep state, the outside world of information input is greatly reduced, many brain cells in a state of "rest".So, this kind of latent lesions abnormal stimulation signals to the brain, can make the corresponding brain cell activity, once the excitement spread to the cerebral cortex, brain cells will stress, so as to appear all sorts of dreams.

Based on the results of the study of American scientists, for several day dream sleep, the deprivation can make people nervous, anxiety, inattentive, easy to anger, and even hallucinations and abnormal behaviour.At the university of Edinburgh, the study found that dream sleep, the brain inside a very active chemical reaction, the brain cell protein synthesis and update peak, accelerate the metabolism, which makes itself does not change the brain cells have a chance to quickly update the protein composition, ready to go into a tense.If you are in the phase of dreamless sleep every night of sleep, that will be laid to rest by the protein in brain cells can not get updated to wake up.It is clear that the dream is so intertwined with life.And different disease is associated with different dreams, the dream of the same diseases tend to be similar.
