　　a dream laboratory at the unlversity of chicago

　a unique laboratory at the university of chicago is busy only at night.it is a dream laboratory where researchers are at work studying dreamers.their findings have revealed that everyone dreams from three to seven times a night, although in ordinary life a person may remember none or only one of his dreams.

　while the subjects——usually students——sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream.surprisingly, all subjects sleep soundly.

　observers report that a person usually fidgets before a dream.once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show .as soon as the machine indicates that the dream is over, a buzzer wakens the sleeper.he sits up, records his dream, and goes back to sleep——perhaps to dream some more.

　researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream.if he is allowed to sleep even five more minutes, his memory of the dream will have faded.

　芝加哥大学的梦幻实验室

　芝加哥大学的一座独特的实验室只在夜间忙碌。它是一座梦幻实验室，研究人员们在那里对做梦者进行研究。研究成果揭示：每个人一夜做梦3至7次，虽然在日常生活中，一个人对做过的梦可能全然没有记忆，或仅能记住个把而已。

　当受实验者——通常是——睡眠时，特殊的机器不仅把预示梦将结束的身体动作记录下来，也把受实验者的脑波和眼睛的活动情况记录下来。说也奇怪，受实验者都睡得很香。

　观察家们报告说，一个人在做梦前总是要翻身的。梦一开始，身体便呈放松状态，眼睛变得更为活跃，好像一场演出已经启幕一样。要是机器显示梦已结束，蜂音器便唤醒熟睡者。他坐起来，记下他的梦中情景，然后再入睡乡——也许去做更多的梦。

　研究人员们发现，假如做梦者在梦后立即被唤醒，通常他能回忆起整个梦的内容；如果让他继续睡，即使只多睡5分钟，他对那梦的记忆也会消失。
