What did Nebuchadnezzar see in the dream Daniel interpreted in Daniel 4?

Answer: A great tree cut down

He dreamed of a huge tree reaching the sky that a holy watcher ordered cut down. Daniel said the tree was the king himself.

“In these visions of my mind as I was lying in bed, I saw this come to pass: There was a tree in the midst of the land, and its height was great.”— Daniel 4:10 (BSB)
