Daniel’s ability to determine and interpret Nevukhadnetzar's dream stems from Divine inspiration and is not mundane psychological proficiency. Both Daniel and Yoseph use Divine inspiration – a combination of faith and intelligence – to interpret the dreams. Prophecy was not an option for them as they both operated in foreign lands, removed from the sanctity and prophetic spirit of Eretz Yisrael.
