For human beings, dreams are still an unsolved mystery. Experts are not sure what the images and feelings of dreams really mean, or they are meaningless at all. Researchers don't even understand the basic question "Why do people dream". . To some extent, this is because people have not fully understood sleep itself. As we all know, sleep is very important to human health, but the real purpose of sleep (rapid eye movement stage, also dreaming stage) is still a mystery to a great extent. In addition, although scientists can monitor people's brain activity during dreaming, the specific content, vividness and disorder of dreams can only rely on the dreamer's subjective description.
Nevertheless, research shows that some types of dreams can reflect physical and mental states. For example, vivid dreams are sometimes accompanied by sleep deprivation, hypoglycemia and pregnancy. Violent or nervous dreams can also reflect your psychological and emotional state. However, it should be noted that vivid or horrible dreams do not necessarily mean that there is a problem with mental health. Nightmares are a very common phenomenon for adults. Although stress or anxiety can lead to nightmares, having nightmares does not necessarily mean that you have serious mental health problems. However, if you have some mental health problems, then some kind of dreams may become one of the symptoms.
Studies have shown that people with depression have more nightmares and more negative dreams than ordinary people. People who have suicidal thoughts are more likely to dream about death repeatedly. However, the dream symptoms of depression are not always the same. Another study shows that in some cases, people with depression will experience "neutral emotions" in their dreams; This may be due to the symptoms of "apathy" in some patients with depression.
Sleep disorder is a common symptom of bipolar disorder/bipolar disorder. Experts say that the main sleep transitions are usually signs of bipolar disorder, including insomnia, always sleeping, and reduced sleep time. Sleep disorders can also affect people's dreams. 1995, a study on patients with bipolar disorder shows that dreams can even predict the upcoming emotional transition. When the patient is about to enter manic state, it is easy to dream of "death and physical injury"; When patients are about to enter a state of depression, the theme of dreams is nothing special, but it will reduce dreaming as a whole.
