Awesome.

I wonder will there be any psychical impact if patient wakes up in the same condition i.e. playing the same media where it left off. Kind of like a dream. Otherwise, they may keep wondering the past. Providing a continuity may or may not play a role here.

Also, the choice of media: I will love to see media company will help to make tailor-made media for this. Like in your case a rocket launch. Think about the impact if it is a famous beloved character rocket. Another example may be a Starwars© theme spaceship launching or a little Mermaid feels sleepy and ready to sleep. I wonder if we can apply autonomous facial auto generation algo. with famous characters to generate story-base, highly customize media to the situation.
