阅读理解。 If your recurring (经常性的) dreams are worryingyou,you can rest assured and needn't worry. Psychologists say in the vast majority of these cases,this is just the mind's way of dealing with stress and conflicts,problems and concerns.It's a good thing. They call be surprisingly vivid and real,or fragmented and weird.They can be comforting or frightening. Our dreams can tell us a lot about what we are really thinking.Dreams give us an x-ray of our unconsciousness(潜意识).They tell us,particularly when we are at life's passages or turning points. Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city. It's always just a feeling of needing to stay safe .Experts say disturbing dreams often occur around major life events.For Lisa,it was moving.For others,it can be marriage or divorce,the death of a loved one or pressure at work. Doctor Siegel has studied the meaning of dream for nearly 30 years.He believes stressful or upsetting dreams can be a sign of what's buried deep inside our minds. He said.'Dreams are important to survival.They are crucial to the balance of our psyche(心灵).They help us work out problems that we're having every single day.They go to the cutting edge of what's stressful,what's bothering us and what we're working out in our lives.Dreams can guide us and in order to f ind that guidance,to find that deep source of wisdom that's in our dreams every night,we need to pay attention to our dreams.' But many dreams are scary and horrible.How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict.The stronger the emotion in the dream,whether it's pleasure or fear,the likeli er the dream is to be important. Knowing what your recurring dreams or nightmares mean can be liberating.Some nightmares can be a sign of serious psychological problems,such as post-dramatic stress disorder.If they are extremely disturbing or violent or the cause of severe anxiety,you should see a professional therap ist (治疗专家). 1.
