During this time, Aunt Zhang always dreamed of her dead wife in her dreams at night, which she thought was a sign that she was going to die. Since then, she felt that her health was getting worse every day, and the children took her to the hospital for examination. As a result, she told Aunt Zhang that she was in good health, but she always felt uncomfortable, her children were anxious, and her family lost their previous laughter. In fact, the elderly dream of their dead relatives for the following reasons. First of all, Kevin Labar of Duke University Cognitive Neuroscience Center found that the unique memory characteristics of the elderly led to their short-term memory difficulties, while their long-term memory was active. This memory feature makes them unable to remember the little things in their current lives, but they are extremely impressed by the painful emotional experiences such as the departure of relatives and friends. This phenomenon is called "emotional memory" in psychology. Second, the projection of the psychological needs of the elderly, the elderly are prone to a sense of worthlessness and fatigue, and their children are busy with work and have nothing to say. The relatives and friends who died in the dream may be the people who can encourage, understand and trust him most during his lifetime, so the old man's inner desire will be compensated in the form of dreams. Third, due to the increasingly weak body, some elderly people have short deep sleep time, insufficient sleep depth and poor sleep quality, which is easy to cause many dreams. For the elderly, dreaming of dead relatives and friends is not a bad omen, and there is no need to be afraid. First of all, the elderly should relax their mentality, actively interact with people around them and establish a harmonious relationship with them, so that those unpleasant little troubles will naturally not come to you. Secondly, develop some of your own interests, participate in some singing competitions, old yangko teams and other activities to enrich your life. Finally, half an hour before going to bed to 1 hour to avoid heavy mental work, you can eat some calming foods such as milk, millet porridge and lotus seed powder. If necessary, you can consult a doctor for some psychological consultation.
