《太平广记·卷二百七十六·梦一》
许攸梦见黑衣小吏为他搬来一张漆案，案上有六封文书，那小吏向他拜跪说：大人应当成为北斗府君。明年七月还有一张漆案，上面有四封文书，那是送给陈康的。
许攸梦乌衣吏，奉漆案，案上有六封文书，拜跪曰：府君当为北斗君，明年七月复有一案，四封文书，云：陈康为主簿。
Xu You dreamed that a black-clad petty official moved a lacquered table for him. There were six documents on the table. The petty official kneeled down to him and said: You should become the ruler of the Northern Dipper Mansion. Next July, there will be another lacquered table with four documents on it. Those are for Chen Kang.
