I once had a dream in which my school bus was consumed by a tornado. As the bus turned and the children flew, everything slowed incredibly. One's perception of time is inversely proportionate to life span. This is why a fly seems to move so quickly; in its vision, you are just slow. It is also why a year when you were five seemed to constitute such a huge fraction of your life. For a five year old, a year is a fifth of their entire life, but for a fifty years old, it is only a fiftieth. So, as my life was shortened by an estimated eighty years, the passage of time compensated for the time lost by slowing. I attempted to use this extra time to think of a way to save myself, and my peers. I tried to grab onto something, but I moved just as slowly as everything else. Then, everything went black. There was simply nothing--no feeling; no sight; no sound; there were only my thoughts. Most of my brain's capacity was expended on supporting my body, and now, with my body dead, that capacity was empty. My brain filled itself with random thoughts. It was everything I could think of, constantly streaming through my attention in flashes, not making any sense. Only one coherent thought prevailed: [i]Is this it? Is this death? Will I be stuck in this maddening darkness for eternity, with these maddening thoughts?[/i] Then, I assume, all the electrons that constituted my thoughts, made their way throughout my body, then to whatever touched it, until my brain became grounded, and it stopped.

That's fair, and although this might either sooth your fears or amplify them, does it really matter if you know or not? There's nothing you can really do to prepare for it, and it's an inevitable fate. You're essentially worrying yourself over something that you have no influence or control over. For some people that thought process calms them and helps them cope with not knowing what's going to happen, but not for everyone.
