I was talking about this with my friend yesterday: We all have heard that right before we die our lives flash before our eyes. What if this "flashback" is done in real time? You would simply live your life, again. Now, if one was unaware that this was a flashback, they would simply start over yes? So what if you re-lived life through the flashback, got to the point of death again, and then the process repeated? Its just one of those dumb ideas that's fun to think about haha
