Bible Verses About Prophets: By dreams and visions

He said to them: Hear my words: if there be among you a prophet of the Lord, I will appear to him in a vision, or I will speak to him in a dream.

And it shall come to pass after this, that I will pour out my spirit upon all flesh: and your sons and your daughters shall prophesy: your old men shall dream dreams, and your young men shall see visions.
