Thou, O king, thy thoughts on thy bed have come up concerning that which is to be after this, and the Revealer of secrets hath caused thee to know that which is to be.

a dream I have seen, and it maketh me afraid, and the conceptions on my bed, and the visions of my head, do trouble me.

As to the visions of my head on my bed, I was looking, and lo, a tree in the midst of the earth, and its height is great:

'I was looking, in the visions of my head on my bed, and lo, a sifter, even a holy one, from the heavens is coming down.

In the first year of Belshazzar king of Babylon, Daniel hath seen a dream, and the visions of his head on his bed, then the dream he hath written, the chief of the things he hath said.
