Speaking as someone who's been trough that, I don't think that the article gives a complete picture. Part of the problem appears to be (particularly by reports from newer generations) in such instaces is the feeling of unreality, as the only times when we tend to see such situations is when we're sitting comfortably, so a lot of us are essentially conditioned to sit comfortably during such events.

However, this does tend to get better with some experience of such situations.
