In episode 8 of Electric Dreams, Impossible Planet, Norton and his coworker at a space tourism company are chartered by an old woman to visit Earth. Norton and Irma seem to be connected in some mysterious way.
Throughout the trip, Norton has various dialogues with Irma, the old woman. Through these dialogues, we learn that Irma's dream is to recreate the the story of here grandparent's thrift in a natural pool somewhere in Carolina. Norton seems to have flashes of a dream that we eventually learn is directly from Irma's dream, and ultimately, after the two of them suffer oxygen deprivation, they have a shared hallucination in which they reenact it in full. There's also the curious detail of Norton being a splitting image of Irma's grandpa, and fitting perfectly in his old clothes.
What was the nature of this connection between the two of them? How did this occur?
