Chief Bromden’s hallucinations are dominated by a thick, debilitating fog that only begins to wane with the arrival of Randle McMurphy to the psych ward. Bromden’s sees the world as becoming increasingly mechanized, and describes the greater society outside and including the ward as The Combine. This fog is symbolic of the waste that our mechanized society has created, and how it pollutes our ability to live naturally. Bromden literally feels as though he cannot see until the antithesis of mechanized control arrives to the ward: McMurphy, a man who looks to his instincts and natural desires for action.
