So what dreams did participants revisit the most often?
什么梦是这些受访者们最常反复梦到的呢？

The age old school/teacher/studying trope ranked number one. Not only had over 80 percent ever had a dream on that subject, but also over 50 percent said they dreamed about it regularly. Over half of the sample also repeatedly dreamed of "searching for a certain place" and "falling."

老学校、老师、学习相关内容位列榜首。不仅80%以上的受访者曾做过关于这个主题的梦，而且50%以上的受访者称他们定期会梦到一次。超过半数的样本也显示受访者反复梦到“寻找某个地方”和“坠落”。
Some of the more surprising findings? "Eating delicious foods" was the fifth most regularly dreamed theme, higher ranked than flying or being chased. Perhaps dieters are seeking out their shunned treats in regular nightly escapes.

有没有更惊奇的发现呢？“享受美食”位于最有规律梦到的主题第五位，排名比“飞翔”或者“被追赶”还要高。或许节食者们都在梦中追求平时望而却步的满汉全席。

Most interestingly, the study found that dream prevalence, recurrence and regularity do not always correspond. For example, 68 percent of respondents dreamed "of being a child again," but hardly any have that dream repeatedly.

最有趣的是，这项研究发现，梦境的普遍性、反复性和规律性并不总是保持一致的。比如，68%的受访者梦到“返老还童”，但这个梦几乎从未反复过。

On the contrary, most had never dreamed of being physically attacked, but those who had were regularly dreaming of it. Likewise, "teeth falling out" rated significantly higher on regularity than on prevalence or recurrence. Ouch.

恰恰相反的是，大部分人从未梦到过人身攻击，但那些曾梦到过被袭击的人会定期做这种梦。同样的，“牙齿脱落”在规律性梦境榜上排名之高甚于普遍性和反复性。

Back to the delusions. While most people wouldn't want to admit experiencing delusions in their waking lives, delusions in dreams were very common. Yu's study found six of the top 20 regular dream themes were delusions. Erotomania, or believing a famous person is in love with you, was one of the most common. One half of participants had dreamt of having a love affair with a celebrity. Romance trumps sex here, because only 22 percent dreamed of having a sexual relationship with a celebrity.

回到幻想上来。虽然幻想在梦境中再常见不过，但绝大部分人不愿承认他们在清醒的时候也产生过错觉和幻想。Yu的研究发现，最富有规律性的20个梦境主题排行榜上，位列前6的内容都属于错觉。被爱妄想症，或者相信名人会爱上你的情况最为普遍。半数受访者曾梦到过与名人谈恋爱。在这种情形中，浪漫胜过了情欲，因为只有22%的人梦到过与名人发生性关系。
