"Are our abilities to have virtual realities in night dreams telling us something profound about how reality works or are night dreams just a isolated product of our imaginations and memories to give us some practice in living and/or to sort out the day’s events?"

Are not our daytime "awake" perceptions and our night time "dreaming" perceptions occurring in much the same way in the brain? When we are asleep, we are paralyzed from the neck down by inhibitory circuits originating in the brain stem so that we won't jump out of bed and act on our dreams. Our dreams are "real" to our neural brain maps, and seem to be resulting in perceptual mapping that "looks like 'external' reality" to our brain. I think this could be "telling us something profound about how reality works".
