Psychological suspense is usually established through a turning point in the plot, conflict, pace, tragedy, raised stakes, or complications. Consider the tone of the passage and how it reflects pace. Perhaps the passage is emphasizing madness or a conflict that has recently taken place. Or perhaps the main character is under a great deal of psychological stress due to a complication or tragedy. Hope this helps.
