Lucid Dreaming - An Example of Meta-Cognition

i love the example of lucid dreaming as an example of metameta consciousness, or meta cognition. So can you give us an example of, like, any evidence that this is the case? Or do you think that, like, this is where future work should go? A mean, how do we do we answer this question? You know, what would be an example of an animal behavior that would hint to us that they do have this ability? i don't have a good answer to that. And the reason is that there are no clear behav ors as of now, bodily behaviors, that indicate explicitly lucid dreaming while asleep.
