I was reflecting, leaving the cinema the other day, on the very clear similarity between the film I had just watched, “Source Code” (2011), by Duncan Jones, and “Groundhog Day” (1993), by Harold Ramis. In the latter, Bill Murray’s character, a stroppy and cynical weatherman finds himself “trapped” inside this Groundhog Day, as it is called, by finding himself forced to relive every single moment of it, from morning till night.

In “Source Code”, Jake Gyllenhaal’s character, an American helicopter pilot, finds himself on a commuter train, “trapped” inside someone else’s body, during the same 8 minutes before the explosion of a bomb that will kill him and everyone else in the train. And then he lives these minutes again, and again, because, it turns out, he is on a mission.

This is the sort of things you see in films or read in novels –"Johnny Took his Gun" by Dalton Trumbo or "The Patient" by Georges Simenon are but two of the examples that spring to mind– but the report that circulates all media since yesterday is very real. A paralysed Belgian man who doctors thought was in coma for 23 years was conscious all along. It was only recently that a scan showed that his brain was "almost entirely" functioning. You can read the BBC report here.

I cannot begin to grasp what it must have been this experience for this poor man, but I can very vaguely imagine. A recent book and film used the metaphor of a diving bell. You are inside your body as if you are inside a diving bell. It's alright when you can control your diving bell. You swim around and interact with all other beings in diving bells you encounter. Suddenly something happens and you loose control of the diving bell. Your life as such is not threatened; but you can't communicate any more, you can't interact. You are trapped inside.
