Daniel
Daniel 2:3ESV·traditional attribution

And the king said to them, “I had a dream, and my spirit is troubled to know the dream.”

John Calvin Reformed @genevareformer

Daniel relates first the great confidence of the Chaldeans, since they dared to promise the interpretation of a dream as yet unknown to them. The king says he was troubled through desire to understand the dream; by which he signifies that a kind of riddle was divinely set, before him. He confesses his ignorance, while the importance of the object may be gathered from his words.

Matthew Henry Presbyterian @wholebiblehenry

We meet with a great difficulty in the date of this story; it is said to be in the second year of the reign of Nebuchadnezzar, Dan 2:1. Now Daniel was carried to Babylon in his first year, and, it should seem, he was three years under tutors and governors before he was presented to the king, Dan 1:5. How then could this happen in the second year?

And the king said unto them, I have dreamed a dream,.... What before is called dreams is here expressed in the singular, a dream; for it was but one dream, though it contained in it various things; this the king could remember, that he had a dream; for it had left some impression on his mind, though he could not call to mind what it was about.
