'Night visions' in the Bible

After this I kept looking in the night visions, and behold, [I saw] a fourth beast (the Roman Empire), terrible and extremely strong; and it had huge iron teeth. It devoured and crushed and trampled down what was left with its feet. It was different from all the beasts that came before it, and it had ten horns (ten kings).

“I kept looking in the night visions,And behold, on the clouds of heavenOne like a Son of Man was coming,And He came up to the Ancient of DaysAnd was presented before Him.
