Dreaming is a normal physiological phenomenon, and the content of dreams varies widely, including pleasant dreams and nightmares. Whether or not a person dreams can be influenced by many factors. If a person frequently dreams, they may wonder about the reasons for this, especially when the dreams are exhausting or nightmarish. We can generally understand the causes of dreaming, and when dreams are frequent, artificial intervention may be possible. So, what are the reasons for dreaming during sleep? Let's take a look below.
Firstly, stimulation from certain events during the day. If you encounter something that makes you feel anxious or afraid during the day, you may have a tendency to dream continuously at night. In such a state, it is difficult to enter deep sleep, and you may clearly feel the events that occur in your dreams. This is because when a person sleeps, some brain cells remain active. When you have something that makes you anxious or afraid, the brain's electrical waves will replay the event repeatedly, thus forming a dream that keeps you from entering a deep sleep state throughout the night, feeling like you are constantly dreaming.
However, this phenomenon does not occur every day, but only when you are strongly stimulated by something during the day.
Secondly, long-term stress. Some people are constantly under pressure in their lives and work. If they are constantly exposed to this kind of stressful situation, it can lead to excessive mental tension. This long-term and excessive stress can also keep the brain cells constantly operating, and such people may even have a worried and unhappy expression even while sleeping. In this state, they may tend to dream more frequently at night.
Thirdly, physical illness. If there is a physical illness, it will have certain specific symptoms. In the early stages, the stimulatory information from the illness to the body is limited and relatively weak in a waking state. However, even very weak stimulation can cause excitement in the cerebral cortex, and ultimately, various morbid and terrifying sensations may appear in dreams during sleep. Therefore, nightmares often indicate the presence of a physical illness.
