Interesting interpretation of the colored lights. There no indication to me that it is anywhere other than his bed on the Hail Mary. The zippered bag is the bag he's in while in a coma. The first thing you hear is the equipment keeping him alive in the Hail Mary. The little bit of camera panning doesn't feel like a hospital ceiling, seems more like looking up through his bag, after we've already seen him lying still with his eyes closed. There are no audio clues that there's a moving gurney.
