3 In a dream, events are altered. A dream may contain parts of many real-life events.Most importantly，something that cannot be shown directly may be shown indirectly.For example, you might dream of driving a large car. This could mean not that you want to have a larger car，but that you desire power，and maybe you want to control other people.Again，you may dream that you are an actor in a play.The play is about to start, but you have completely forgotten your lines。This dream may seem strange because you are not interested in acting, and you-never want to be in a play.But the dream may mean that you have some other problem that you feel is too difficult for you to solve. 　　4 Psychologists believe that dreams may be helpful to us. Indeed，people who have been allowed to sleep in experiments, but not allowed to dream，have become anxious and restless.And when they are later allowed to sleep as much as they like，they dream more than ever to make up for the lost dream time.
