I’ve watched a documentaries and read stories about the people who have missed doomed flights, and they’ve never failed to give me a chill. For several of these people, the premonition factor had nothing to do with why they never made it to the airport. Life made the decision for them, either through a subconscious choice or outside forces, such as their car breaking down.

The remaining would-be passenters experienced uncharacteristic anxiety attacks (or an overwhelming sense of dread that they couldn’t shake) that caused them to miss their flights. They took the next flight or stayed home, feeling like a crazy person. Later, they would hear that their intended flight had crashed, killing most or all on board.

For most people, the difference between a fear and a premonition is that fears are vague and not unusual. Premonitions, on the other hand, seem to come spontaneously, and often with great force and clarity. In fact, for most people, the problem is not recognizing a premonition, but acting upon it.

The Atlantis Rising article (see link above) give some chilling accounts of premonitions of famous disasters. I’ve included links to a more articles below, but the Atlantis is the best one on the subject.
