first of all and i like very much the central idea of locate the intruder and others in the fragile self and on various level mainly subconscious but sometimes more allegorical . in fact the intruder be omnipresent throughout the film represent in the swiss french border where the pretagonist lead seclude life while in the his recurring daydream and nightmare while inside his ail body after heart transplantation . in the last half of the film and he become intruder himself and return in ancient french colony in the hope of atone for the past . the overall tone be bitter rather than pathetic and full of regret and guilt and sense of failure be more or less dominant . this be a quite grim picture of an old age and ostensibly self dependent but hopelessly void and lonely inside . the directer compose the image more to convey pass sensation of anxiety and desire than any explicit meaning . some of them be mesmerize and not devoid of humor though and kind of absurdist play only somnambulist can visualize .
