Setting aside the truth value of the UFO phenomenon, it is an interesting sociological reality that so many people are unwilling to discuss the most - and at times traumatic - experience of their lives. What does it say about our society that this is so? My feeling is that, by its very nature, it represents a form of repression. If you are a reader who believes UFOs to be nonsense of some sort, I can nevertheless assure you that you have a friend or relation who has seen one. They have simply learned not to discuss it. Many people can live perfectly well within the constraints of repression and denial; they simply learn to shut off certain parts of their mind. It is sad, but it happens all of the time.
But not everyone is the same. Not everyone is willing to do this, or even can do this. By any estimate, there are may millions of people on this planet who have had a powerful UFO experience. They cannot and will not be silenced indefinitely.
