'Visions' in the Bible

Now the rest of the acts of Solomon, first and last, are they not written in the book of Nathan the prophet, and in the prophecy of Ahijah the Shilonite, and in the visions of Iddo the seer against Jeroboam the son of Nebat?

And he sought God in the days of Zechariah, who had understanding in the visions of God: and as long as he sought the LORD, God made him to prosper.
