Faulkner, the mind, and real life (Punctuation is important)

It seems to me that Faulkner uses punctuation in Quentin's section, and to a lesser degree Benjy's section, to blur the line between real and internal life. Quentin is an inwardly focused character, and the uninterrupted transitions between his own thoughts and concerns and frets and the details of his present situation serve to place Quentin's section on a really fuzzy line between events and considerations and the importance of these to the story. This all falls into line with some of Faulkner's opinions on the nature and importance of the past, that past events are equally important to a narrative, if not more so, than the events of the present. This ambiguity of time in the novel creates a sense of fatalism, the entirety of the narrative arc contained less in a line than in a single dot, the ends of the characters as predetermined and unchangable as their beginnings.
