We, humans, use dreams for consolidating memory and information recall, process emotions and rehearse feelings in different imagined contexts, mental housekeeping / pruning away partial or unnecessary information, replay recent events to review and analyze, etc. Dreaming and sleeping is incredibly expensive, we spend 33% of our "availability" on average asleep. This kind of work is a step toward building similar tools for general AI agents (IMHO).
