'Visions' in the Bible

Now as for these four youths, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams.

but there is a God in heaven who reveals secrets, and he has made known to the king Nebuchadnezzar what shall be in the latter days. Your dream, and the visions of your head on your bed, are these:

I saw a dream which made me afraid; and the thoughts on my bed and the visions of my head troubled me.

Belteshazzar, master of the magicians, because I know that the spirit of the holy gods is in you, and no secret troubles you, tell me the visions of my dream that I have seen, and its interpretation.

Thus were the visions of my head on my bed: I saw, and behold, a tree in the midst of the earth; and its height was great.

I saw in the visions of my head on my bed, and behold, a watcher and a holy one came down from the sky.

In the first year of Belshazzar king of Babylon Daniel had a dream and visions of his head on his bed: then he wrote the dream and told the sum of the matters.

After this I saw in the night visions, and, behold, a fourth animal, awesome and powerful, and strong exceedingly; and it had great iron teeth; it devoured and broke in pieces, and stamped the residue with its feet: and it was diverse from all the animals that were before it; and it had ten horns.

I saw in the night visions, and behold, there came with the clouds of the sky one like a son of man, and he came even to the ancient of days, and they brought him near before him.

As for me, Daniel, my spirit was grieved in the midst of my body, and the visions of my head troubled me.
