Isaiah's Dream

Can God use dreams to teach truths? I think He can, and I'm wondering if He did with Isaiah recently.

Isaiah, one of my sons, explained a dream he had. Here it goes:

There was a heart. In the heart was a person's spirit. It was black. Then God's Spirit entered it. That was orange. Isaiah said that each spirit looked like a squished diamond. While God's Spirit was in the heart, it shot the black with fire, and the black was thrown out of the heart. Then the heart slowly became white.

I'm not sure on the meaning of everything, but this is pretty descriptive and cool! Very interesting, very precise, and there are definitely lessons that can be learned from this.
