Daniel interprets King Nebuchadnezzar's dream and earns his good graces (Daniel 2:19 - 2:49) - Bible Blender
What the “vision” refers to is not specified. It may have been a physical manifestation, a dream, or merely a thought. At its root, it was wisdom. The first thing Daniel does when the King’s dream is revealed to him is to acknowledge that God revealed the dream and thank God for giving him insight.
