According to the author, split-second impressions form a ‘mental state, not an actual story, but one abounding in fertile associations and images’.
Compare this with Virginia Woolf’s experiment with the stream of consciousness technique in ‘The Mark on the Wall’.

Split Second Impressions is what Bergman associates with the beginning the film that is very vague but agreeable event which disappears as they come and leave behind a mood. He says that this is a mental state, not an actual story being a brightly coloured thread sticking out of the dark sack of unconsciousness. With the accumulation of all these threads, one can carefully weave a complete film but it requires patience and a pattern in accordance with these rhythms, obeying laws born out of and conditioned by his original stimulus can gain enough strength it could be made into a film. It requires proper analysis of the Impressions; Its rhythms, moods, atmosphere, tensions, sequences that give a perfect screenplay.

Whereas the Mark on the Wall Summary by Virginia Woolf is a first-person narrative recalling the past and specifics of an event. The narrator beautifully crafts his stream of consciousness into words that try to reflect and associate a series of event with a singularity of a mark on the wall. The process of thinking exhibits a spectrum of event related to the one being discussed and shows how vivid a mind could be.
