The Cabinet of Dr. Caligari has two very important narrative features. First of all it is a silent film and so a great deal of the plot and storyline is told through the use of captions. This means the audience has to read and is atleast partially responsible for the message delivered in this, as with reading a book, which this form of cinema is a step closer to, there is more chance for ambiguation. The second aspect of this films narrative which is of great interest, is that the narrator of the story can not be completely trusted. The story is told in the first person by our hero Francis, but by the end of the story we come to realize he is actually telling the story from the grounds of an insane asylum and that he is likely not of sound mind himself. The film switches out of first person narration which changes the understanding of the story completely from a tale of tragic and mysterious events to simply the ravings of a lunatic.
