Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease.
Recent research results also confirm this view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body, and dreams are the need for the healthy development of the brain and maintaining normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases. : "I think every day and dream at night." Things that bother you in reality will be alluded to in dreams.
You said you dreamed of going to jail, maybe there is a "besieged city" in reality that imprisons you.
But generally speaking, dreams and reality are opposites.
As long as the mentality is calm and calm, this is not a big problem.
