I don't think it's that at all, my interpretation was that that's his mum in a coma and the things in the room are influencing the things she's seeing in the coma. She has the Sharman patterned throw so she sees that, the doctor is telling the boy a story about something shooting across somewhere and she sees that in the the sky in her coma. She's waiting to be rescued and woken up.
