Midrash for Daniel 2:31

(Gen. 41:8:) < AND IT CAME TO PASS IN THE MORNING > THAT HIS SPIRIT WAS TROUBLED (rt.: P'M), in that it was beating against him like a gong (rt.: P'M). Another interpretation (of Gen. 41:8): THAT HIS SPIRIT WAS TROUBLED. It is written of Nebuchadnezzar (in Dan. 2:1): HIS SPIRIT WAS DEEPLY TROUBLED; and it is written of Pharaoh (in Gen. 41:8): THAT HIS SPIRIT WAS TROUBLED.¹³Tanh., Gen. 10:2; Gen. R. 89:5. Why? Pharaoh knew the dream but did not know its interpretation; therefore, he was confused by one confusion. But Nebuchadnezzar knew neither the dream nor its interpretation; therefore, < he was confused > by two confusions. Thus it is stated (in Dan. 2:1): NEBUCHADNEZZAR DREAMED DREAMS. R. Hiyya said: He dreamed one dream. Then why does it say: DREAMS (in the plural)? Because he had forgotten the dream. R. Jannay says: He dreamed two dreams, one of an image (in Dan. 2:31-35) and one of a tree (in Dan. 4:7-14).
