I think it's about a man's hallucination talking to him and giving him solace in a lonely world.
The hallucination/dream-friend only appears in the writer's sleep, so asks where he had been. And the dreamer/writer tired of loneliness, when falls asleep is provided comfort by the friend. Who assures him there is no need to let the isolation defeat him for he is there for him.
