Like I said earlier, some of these things are weaker than others. That was an example of a weak Kaidan quote. Here's a stronger one.
Kaidan: "People near death say their lives flash before their eyes... The future flashed for me--the anguish, the families, the children... It made me determined to live."
The secondary meaning there, to me, can be an explanation of what Shepard sees at the very ending of the game after making his "choice". In the original game, that's the Normandy crash. In EC it's also his own funeral and whatever monologue about the outcome of his choice is appropriate. It's all a near-death vision. If you're (un)lucky, you wake up from that illusion in the breath scene to find yourself in the rubble.
It's all an interpretation. It might be true or it might not. I need a Mass Effect 4.
