'Visions' in the Bible

Now as for these four young men, God gave them knowledge and made them expert in all book-learning and wisdom: and Daniel was wise in all visions and dreams.

But there is a God in heaven, the unveiler of secrets, and he has given to King Nebuchadnezzar knowledge of what will take place in the last days. Your dreams and the visions of your head on your bed are these:

I saw a dream which was a cause of great fear to me; I was troubled by the images of my mind on my bed, and by the visions of my head.

In the visions of my head on my bed I saw a watcher, a holy one, coming down from heaven,

In the first year of Belshazzar, king of Babylon, Daniel saw a dream, and visions came into his head on his bed: then he put the dream in writing.

I saw in visions of the night, and there was coming with the clouds of heaven one like a man, and he came to the one who was very old, and they took him near before him.

As for me, Daniel, my spirit was pained because of this, and the visions of my head were troubling me.
