For centuries, people have wondered about the strange places that they seem to visit in their sleep. 1 However, they have been valued as necessary to a person's health and happiness.

It was only in the twentieth century that people started to study dreams scientifically believing that they tell about a person's character. 2 He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.
The second theory to become popular was Carl Jung's compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer. 3 Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.

Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance,

小题3:A 根据下句hus, people who think too highly of themselves may dream about falling;对自己有很高评价的人在梦境里也许会遭遇失败。说明A项梦境弥补了在现实生活中所缺少的东西。故A正确。
小题4:E 根据下句Until they reach age five,直到五岁，说明这里叙述的是孩子的话题。故E项符合上下文。
小题5:B 根据下句If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.说明我们不要把梦境当成真的事情，故B下符合上下文。
