Why do people dream when they sleep?

Answer 1

We dream because the wise unconscious that regulates the functionalism of our bodies can treat the human conscience and help it fight against the anti-conscience without its interference, as is the case when we are awake. In your dreams, the unconscious gives you directions, warnings and psychotherapy. You need them, because insanity is inherent in the anti-conscience that constantly tries to destroy your human side. While you are sleeping, you can be in contact with the unconscious that works like a doctor in your psyche and sends you dreams in order to provide you the guidance you need.
