Individuals high in trait openness tend to have vivid dreams, an interest in mythology, and are drawn to psychologists who share these traits. In contrast, individuals low in openness often do not recall their dreams and are less interested in psychological narratives, focusing more on practical applications. Professionals like lawyers and physicians are typically higher in trait conscientiousness, prioritizing practical psychology over narrative aspects. The speaker doesn't fully agree that consulting Jung leads to 'Jungian dreams' and consulting Freud leads to 'Freudian dreams'.
