《资治通鉴·魏纪·魏纪四》
后来刘晔单独晋见，责备明帝说： 讨伐一个国家，是一项重大的决策，我知道这件大事后，常常害怕说梦话泄漏出去增加我的罪过，怎么敢向人说这件事？
后独见，晔责帝曰： 伐国，大谋也，臣得与闻大谋，常恐眯梦漏泄以益臣罪，焉敢向人言之！
Later, Liu Ye met the emperor in private, he accused Emperor Ming of: Attacking a country is an important event, after I heard about this important event, I often had nightmares, fearing that I would accidentally leak the plan and increase my sins, how could I dare to talk about this with others.
