简介：
Troubled by bouts of sleepwalking and disturbing nightmares, graduate student Sarah Foster goes to her university sleep research center for help. But when she wakes up after her first night of being monitored, the world she lives in seems to have changed in subtle, Twilight-Zone-esque ways顾客：“老板，你家的米饭怎么这么硬？”老板：“先生，这叫‘有嚼劲’，锻炼您的咬肌，预防老年痴呆。”顾客：“……那给我来一份‘老年痴呆’的。”老板：“我们没有这种米。”
