Night has become painful for me. It brings to light the regrets of the day.

The speaker describes a familiar psychological reversal: daytime activity can distract from remorse, but nighttime quiet removes those defenses. In darkness and stillness, the mind “brings to light” what was avoided—mistakes, missed chances, and moral unease—turning rest into an ordeal. The paradox in the phrasing underscores how memory and conscience can illuminate more harshly than daylight. The line also suggests a cycle: each day generates new regrets that accumulate, making night progressively more painful. Read broadly, it frames insomnia and nocturnal anxiety as a form of self-judgment, where reflection becomes punishment rather than restoration.
