What does Sam suggest as a reason for Charleys experience?

In The Third Level, Sam suggests that Charley’s experience on the third level is a result of “waking dream wish fulfillment.” According to Sam, Charley’s vision of the third level is not real but rather a psychological response to his overwhelming desire to escape the anxieties of modern life. Sam believes that Charley’s mind has created this imaginary space as a way to find relief from the stress, tension, and fast pace of contemporary society. Sam’s explanation reflects the theme of escapism, implying that Charley’s longing for a simpler past has manifested in a vivid, dream-like experience.
