What does Daniel 4:18 mean?

That’s the dream I, King Nebuchadnezzar, had. Now, Belteshazzar, tell me what it means. None of my wise men can explain it, but I know you can, because the spirit of the holy gods is in you. Daniel 4:18 - Modern Text Bible

(Nebuchadnezzar admits he doesn’t understand the dream and asks Daniel (Belteshazzar) to interpret it, trusting in Daniel’s spiritual insight.)
