Dreams are necessary in our life. We know that about 25% of our _ 21__ time is spent dreaming. This is true for everyone, whether you are the kind of person who ordinarily remembers your dreams or not. Often our dreams show us “the other side of the picture”,   22   us aware of the things we have failed to take conscious   23   of during the day. For instance, if you dream that your new boss, who seems gruff (语言粗暴的) and unfriendly during the working hours, is smiling at you and   24   you for your work, perhaps you have subliminally (下意识地)   25  up signals that day that his bark is worse than his bite.
All of us need dreams, and the   26   we are, the more necessary they appear to be. Babies spend   27   half their sleep in the dreaming phase. When adult subjects in an experiment were given drugs that eliminated（排除）their   28   for several nights, they became increasingly irritable（易怒的） and   29  , and often began having difficulty concentrating. Too much dreaming appears to have its drawbacks too. If you doze late on Sunday mornings, you often wake up feeling tired. The   30   is that the more you sleep, the longer your dreams become.
