I have a wild and semi-unprovable theory that whenever you feel fear in a life-threatening situation, you are in fact feeling the simultaneous multiple-universe death of your other selves who don't survive the life-threatening situation -- sort of the way identical twins report that they can sense each other's feelings, or know when the other is in danger. It's probably total BS, but it's fun to think about.
