One must balance that against the poor writing which is previously foreshadowing the existence of a character, having a mysterious figure show up, and then connecting the two in the very next episode. With the dream, it allows them to string it along further (not that there's much point for us) for the characters involved (especially the one with the great personal connection) to wonder at their benefactor, and give Yang significant hope as her subconscious latches onto the figure and lights a fire in her brain. This lets her quest continue, when previously she had just about run out of leads.

You seem to imply that the dream pertains to resolving character arc issues. I say quite the opposite. Nothing is resolved by the dream. Rather, said issues become more complicated. If they had met in the waking world, such issues would be resolved. You simply don't establish that a character has a long-term quest, then instantly resolve it a few episodes later (as you seem to be proposing). That's a copout. You must show them engaged in it. And what better way than to suddenly get a new lead?
