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.
