The character in Jim Thompson's "Pop. 1280" experiences a moment of realization about his reality, as the effects of alcohol intensify his awareness of his surroundings. He comes to terms with the difficult circumstances he is in, and this realization is profound and painful.
This awakening occurs after consuming a significant amount of liquor, illustrating how substance use can both numb and expose deeper truths about one’s life. The imagery of being "soaked clear through" suggests a struggle with his situation, as the alcohol serves as both a temporary escape and a harsh lens through which his raw feelings emerge.
