《北史·列传·卷五十八》
他的伯父柳庆远特别器重他，对他说： 我昔日侍奉伯父太尉公，伯父曾对我说： 我昨夜梦见你登上一座高大壮丽的楼房，我把座席交给了你。
其世父庆远特器异之，谓曰： 吾昔逮事伯父太尉公，尝谓吾云： 我昨梦汝登一楼，甚峻丽，吾以坐席与汝。
His uncle, Liu Qingyuan, admired him greatly and said to him, “In the past, I served the Minister of War who once told me, ‘last night I dreamt that you had ascended a tall and majestic building, and I gave up my seat and let you sit in it.’ You will surely achieve great fame and rank, but it is a pity that I will not live to see it. I also had a nap during the day and dreamt that I returned the seat that I previously gave you, so your official rank should be as high as mine. You must work hard to live up to this auspicious sign.”
