I think Deok Im being in the afterlife with San makes sense. Remember in the episode earlier when she made the oath with her friends to meet in the afterlife and then she says what if someone breaks it. I thought she was referring to herself.
That's how I'm choosing to see it, too. I don't think that was San's dream, I think that was truly their afterlife. She chose to be there, she chose to receive him and hold his hand to go away together, fulfilling the oath in the poem they read together.
Imo reading this scene as San's fever dream only is very unsatisfying for me, too. She loved him, and only in death was she able to stop deceiving herself. I like to think that this is also a fulfillment of Deok Ro's dying wish. San realized he did need her love, not just to possess her, and Deok Im found him again outside the shackles of the palace, which she also wanted.
