This is easy. The Surah I believe that this is quoted from is Surah An-Nur 24:40? Am I right?
Or [the state of a disbeliever] is like the darkness in a vast deep sea, overwhelmed with a great wave topped by a great wave, topped by dark clouds, darkness, one above another, if a man stretches out his hand, he can hardly see it! And he for whom Allah has not appointed light, for him there is no light.
It is talking about the state of the disbeliever. If you read this in context to the disbeliever as it is mentioned; I don't think you can take this in the literal sense. When I read it, all I see is a visualization of the disbeliever being in darkness. Like the darkness of the vast deep sea. With wave upon wave between him and the surface. If he reached out his hand in front of him he will not be able to see it. Such darkness.
It would be a big stretch to take it as far as the Youtube video has taken it. But then again when you have faith you see what your eyes want to see. It is only human. :)
