In point of fact, millions of dead and injured human beings, and more than millions of shattered and an extremely traumatic, shell shocked and deeply wounded psyche have been left by The Great War. Indeed, mankind’s collective psyche remained tremendously wounded and shocked, if not permanently, for a long time. Undoubtedly, no one was safe and secure of being influenced severely by the harms and damages of the war. The growing conflicts that led to the World War One made people live in unceasing psychological stress and trauma. Moreover, the influence of the Post-Traumatic Stress Disorder on most of the writers and poets, including Siegfried Sassoon and Wilfred Owen was very deep and obviously reflected in their writings.As a matter of truth, this study proposes to discuss Siegfried Loraine Sassoon (1886-1967) andWilfred Edward Salter Owen’s (1893-1918) poetry in the light of the Freudian Psychoanalytic approach to find the real meaning of the work of art through penetrating the truth out of the mind of the writer. The World War One had a huge impact on re-examining Freud’s view of dreams taking into considerationharrowing events including shell-shock, suffering, mental pains as well as trauma where the patient relapsed in his dreams to the very situation, distressing as it was, which had hastened his neurosis.
