This can best be understood by comparison to the phenomena of thought and speech in the soul. Every letter which emerges in thought and speech is drawn from the inner essence of the intelligence and emotions of the soul. B efore Hashem's letters of creation combine into words, they are still unable to give life to individual creatures. Thus, the inner life of every creature is its Hebrew name. Thus, by uttering the letters of Torah and tefila , the Jew becomes a partner bound with G-d in the action of creation.
D reams are the imaginary visions of the act of creation that appear to the soul in exile.
They represent spiritual or material ideals that are foreign and unreal, the pursuit of identity void of foundation. The only foundation upon which the Jew can establish his identity is Torah and mitzvot. Internally inconsistent and disordered, dreams leave the life of the spiritually exiled Jew meaningless. The Jew possesses a unique, innate sense of purpose. Purposeless existence can cause him only frustration and despair.
