The consciousness of lucid dreaming is a cultural evolution. It's something that we are talking about and learning about, not biological evolution.
Stephen LaBergeThere is only one essential difference between consciousness and dreaming, and that is sensory input. Your experience is a dream, so is my experience. This stuff about how the frontal cortext is repressed during dreaming. Lucid dreaming presents an obvious contradiction to it. The only difference is sensory input.
