Analyse narrative et flux de conscience : Mrs Dalloway

Read the following extract from Virginia Woolf's Mrs Dalloway (1925) and analyze the narrative technique used: 'For having lived in Westminster—how many years now? Well, over twenty years, surely—she felt very young; at the same time unspeakably aged. She sliced like a knife through everything; at the same time was outside, looking on.' 1. Identify the literary technique where the narrator shifts between the character's internal thoughts and the external setting. 2. Explain how the punctuation (dashes and semicolons) contributes to the rhythm of the character's mind, considering the mental frequency $f$ of thoughts as a metaphor for the flux of time $t$.
