I believe dreams are important and serve in many ways.
Primarily the two that seem to stand out are either a purge of sorts or that in which the conscious is able to travel freely or simply put intuitive aspects of ourselves.
That's where inspirations, answers to questions we may not be able to reach in our waking state, reach.
I believe as well, during the dream state, depending which one we happen to be, we're quite able to connect and/or RE-connect to those whom we have either emotional connections to or those we don't REALIZE we DO have connections to that seep in when one or the other happens to delve in their own consciousness, when we may not physically BE there to witness such a thing
