I dunno about that Brother. God is pretty big on symbolism and there's a scripture which says He'll send us dreams.
Acts 2:17
17 And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:/
God has a lot of different ways to communicate with man. Personally, I feel that speaking words is prolly the most in-efficient way to communicate, That's prolly why God seems to use dreams and visions so much in scripture, because a picture is worth 1000 words and people get more out of it with the pictures. He did a lot of that sort of thing in the past and there's no reason to think He would stop, right?
