A dream is made up of a series of mind?pictures that form during sleep.The people and actions in these pictures seem real to the person who is dreaming.?

Dreams may be influenced(影响) by different things that are present during sleep.If a person is cold,he may dream that he is out in a snowstorm.Worries or anger may also influence the content of a dream.?

Some people think that they seldom dream,other people are quite sure that they do not dream at all.Studies of human sleep have shown,though,that everyone dreams every night.If a person thinks he does not dream,it is because he does not remember dreaming when he wakes up.Usually,a person may dream three to seven times for a total of one to two hours of dreaming every night.?

Perhaps you are wondering just how research workers can be sure that a person is dreaming.The story behind the discovery is an interesting one.?

During their research studies of human sleep,Dr.Kleitman and his assistant noticed that a person sleeping made sudden eye movements.These movements occurred at least several times a night.When a sleeper was awakened during these periods of eye movement it was learned that he had been dreaming.In most cases,the dreamer could then recall(回忆) his dream.The person's eye movements,scientists believe,were caused by the movements of his eyes as he followed the events of the dream.?

Not only does everyone dream,but it seems that we all need to dream.One theory is that dreaming gives us a chance to escape from the rules of our real world.In dreams we can see our wishes come true.We can be rich,powerful,and successful.?

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
　　I am one of those unlucky people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the place I was heading for.
　　I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit（承认）that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite（相反的）direction to that in which you should be going.
　　If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
　　Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
　　Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.
