Scripture also shows that true prophets of the Lord have visions, not dreams, but these visions are given in order to edify the church, not scare the masses silly. We don't need no stinking visions of the end of the world. The world was overcome when Jesus was resurrected. We need to just keep our shoulder to the plow, do our work and carry on, even as it happens. There is one Ark, and we should spent our last days and last breath, telling the cattle to get in.
Certainly Jesus is to be our focus.
However, Holy Spirit does give dreams to some prophets as He does to people of all roles. He's not exactly
limited,
you know.
I believe they are at least given for prayer. But also for preparing one's heart and mind; changing one's ways and/or location; being more in tune with what God's about to do, etc.
