虛幻文學創造出現實生活中不存在的事物，以及日常法則無法解釋的事件，由於它超越經驗認知的局限，作者可以開創其獨特的視野，對現實世界進行深刻的觀察，而賦予作品更豐富的精神價值。李白藉由「龍」物象，將在現實世界中被認為是荒誕、虛幻、變態的事情合理化，建立一個虛幻文學中的心理時空世界，借乘「龍」入仙境側寫人間的困頓，開啟了幻想與現實的對照比較，彰顯出人類世界的本質特徵，並流露出更多對人世的關懷之情。本文從「乘龍飛入虛幻神仙世界」與「龍各具姿態的活躍靈動性」二大面向來探討李白詩中「龍」物象由虛幻到現實的影射，追尋其獨特而深刻的觀察，重現諸如「從政用世的企求與艱險」、「詭譎世情的體悟與成慨」、「君王縱情聲色的否定與託諷」、「歷史興亡更替的透視與省思」、「功名富貴的消解與淡漠」等真實感受。

Fantasy literature creates unreal things and unexplainable events that go behind our experience and cognition. The authors can thereby develop their unique vision to observe the world deeply, and thus make their writings much richer of spiritual values. Li Bai used the images of ＂dragons＂ in his poems to rationalize the things that were considered absurd, illusory and perverted in the real world. In doing this, he built a fantasy world where he could ride a dragon highly into the sky and overlooked the real-life difficulties over there. He wrote the actual world by comparing it with the view of mirage; this way he had explored the essence of human society and revealed his concerning to the people. In this article, we study the phantom and the projection in Li Bai's poems from two viewpoints, i.e., ＂flying a dragon into the fairy world＂ and ＂the smart actions and transformations of dragons＂. Following Li Bai's unique and profound observation, we can almost feel those situations in history, such as ＂the aspiration and difficulty on contributing oneself to the people＂, ＂the experience and emotion about the treacherous world＂, ＂the ridicule and admomsh to the emperor's debauchery＂, ＂the perspective and reflection to the history of rise and fall＂, and ＂the understanding and indifference to the fame and fortune＂.
