《左傳》中許多戰爭的背後，多有其相關聯的夢。「夢與戰爭」的關聯如何聯繫政治發展的過程，解釋權力消長的關鍵，便是本文所要討論的重點。在晉楚相爭的最後一戰「鄢陵之戰」的過程中，晉將呂錡夢見「射月」與「退入於泥」，表面上似乎與戰事不相關聯，歷來論者也甚少提及，但《左傳》對整個歷史脈絡的安排，平白記載一個不重要的插曲，實是匪夷所思。故筆者擬先分析鄢陵之戰時的晉楚形勢，以及晉勝楚敗的關鍵與影響。而後透過呂錡之夢，了解《左傳》在一貫的預言模式下，以天命思想呈現禍福敘事，呂錡夢兆正是對晉楚兩國命運的最佳註解。鄢陵戰後，厲公削弱了楚國問鼎的氣燄，為晉國開啟了復霸之路，但是戰爭的勝利，對於厲公本身以及當時晉國國內的情勢卻產生了極大的矛盾與不利。
