Could it be that the circumstances surrounding this event are being repeated, or so similar, that you see it building up to what you predict. People
who are not alike, often react in the same way to circumstances.
If someone yells fire, almost every one can be predicted to react similarly.
If someone hollers "duck" people react pretty much the same.
If you are talking about the same people and similar events, that may explain it.
Maybe you are a person observer. You watch people's reactions, study people, know alot about human nature, etc.
