1. We know a lot about why we sleep. Fx.: The brain has a slightly higher metabolic rate, but is relieved of reactive thoughts and complicated motor-calculations. It's also free from selecting among sensory input and reprieved from the necessity of suppressing those deemed less important.
2. Instead it's free to dream, and much of this revolves around resolving loose ends of the day by running different scenarios.
Dreams also organize new learnings into the hierarchy of personal experiences.
It's very easy to discern what dreams do by skipping sleep a few days. Lacking the restoration of the calmer mental states, an increasing mental alertness sets in. Perception becomes less selective. Most people become hypervocal and hyperactive. Gradually learned inhibitions weaken and the person starts appearing slightly manic. Muscle tone increases and so does metabolic rate, albeit gradually.
The lack of integration of new learning eventually shows up as deteriorating judgement and the more basic, animal instincts become more prevalent at the cost of social skills.
3. Consciousness is not a "what", though. It is much, much more essential.
Consciousness is the only absolute no-thing in the universe and uses no time – is in effect "eternal".
It's not a product of anything or any thing. It is entangled with all matter, whether in the organized form in organisms or less organized forms of "pure matter" – which is of course never really pure.
4. Yes, we most certainly do have free will, but we also have fate. There are absolutely no restrictions on our free will whatsoever! Some even willfully choose to live most of their existence without ever exercising it. But truly free will necessitates awareness of consciousness...
5. Things all have their distinctive reality on different levels of existence, but no reality on any level can be said to be objective, as all objectivity is irretrievably entangled with the innumerable and slightly different perceptions by subjects.
