This essay discusses how Eugene O'Neil's "Long Day's Journey Into Night" uses the Freudian theory of the unconscious in the stream-of-consciousness dialogue. The play is about a dysfunctional family, whose summer on the shore is filled with abuse of alcohol and drug addiction. Yet the family is in severe denial about this abuse. In this context, we see Freud's theme of how the unconscious operates. 10 pgs. Bibliography lists 5 sources.
