What is the survival advantage of (and the evolutionary process that lead to) a species developing the ability to dream?

Help me figure out this evolutionary process.
So once there was a time when no organism dreamed. A single random mutation in a single organism cause its pineal gland to manufacture dimethyltryptamine. Its offspring inherited the trait, and due to some environmental pressure, they received some degree of survival advantage from it.
Do I have this evolutionary mutation process laid out properly? How else would could the dream state have appeared? What environmental pressure did it overcome? And why would it leverage an advantage to a species survival?
