　　芝加哥大學(xué)有一個(gè)特別的實(shí)驗(yàn)室只有在晚上才繁忙。這是一個(gè)進(jìn)行夢(mèng)的研究的實(shí)驗(yàn)室。在這里研究人員對(duì)做夢(mèng)的人進(jìn)行研究。他們從研究發(fā)現(xiàn)中總結(jié)出每天晚上每人都做3—7個(gè)夢(mèng)，盡管通常情況下一個(gè)人只能記住一個(gè)或忘記他所做的全部的夢(mèng)。
　　當(dāng)被研究對(duì)象睡眠時(shí)，特殊的機(jī)器記錄下他們的腦電波、眼球的運(yùn)動(dòng)及表示夢(mèng)結(jié)束的身體的運(yùn)動(dòng)。令人驚奇的是所有的被研究對(duì)象都睡得很熟。
　　觀察人員發(fā)現(xiàn)人在做夢(mèng)之前身體會(huì)不安地移動(dòng)。一旦夢(mèng)開(kāi)始了，身體會(huì)放松，眼部則開(kāi)始活躍起來(lái)，就像帷幕已經(jīng)拉開(kāi)，演出即將開(kāi)始。當(dāng)機(jī)器表明夢(mèng)已結(jié)束時(shí)，蜂嗚器會(huì)叫醒睡眠者。他會(huì)站起來(lái)，記錄下他的夢(mèng)，然后繼續(xù)睡，或許會(huì)做更多的夢(mèng)。
　　研究人員發(fā)現(xiàn)如果一個(gè)做夢(mèng)的人在他的夢(mèng)結(jié)束之后馬上被叫醒，那么他一般能夠回憶出整個(gè)的夢(mèng)。如果他再睡上5分鐘，對(duì)于夢(mèng)的記憶就會(huì)逐漸消失。這就是為什么大多數(shù)人晚上做很多夢(mèng)，但早上卻幾乎都不記得了。
