The document discusses two types of time: clock time and psychological time. Clock time is objective and linear, measured by minutes, hours and years. Psychological time is subjective and nonlinear, as perceived by the human mind. In Virginia Woolf's novel "To the Lighthouse", she uses interior monologues to show characters experiencing compressed or extended psychological time compared to objective clock time. For example, Lily Briscoe has moments where she recalls past events or finishes her painting after being stuck for years. The document analyzes how Woolf represents the difference between clock and psychological time through the experiences of characters in the novel.
