Heart of Darkness - the psychological journey

As the reader travels with Marlow through the Heart of Darkness up the Congo river, the reader is able to actually experience the adventure that Marlow is experiencing. Marlow's descriptions become choppier throughout his journey, referring to his psychological state of mind which is constantly changing. As he travels up the river and is exposed to different people and different settings, Marlow's language and feelings become more unconscious and less meaningful in a way, as he travels into the darkness that he is never exposed to while in London. The trip Marlow takes transforms him and exposes him to a great deal of mystery and wonder, which ultimately causes Marlow to be unconsciously anxious to keep going and going deeper into the heart of darkness. Therefore, his journey is most definitely a physical journey, but it is most importantly a psychological journey into the unconscious.
