I guess lucids can be more real than WL because they are not constrained by the sensory input. When awake it would be dangerous from an evolutionary sense to augment reality, because that would be false information about the real world. In deans, lucid or not, the only reference is our imagination, so it makes sense that everything can be just a bit more vivid and intense. The other thing that could be going on is that maybe the brain chemistry when lucid makes us a bit high?
