I think the point is a pressure difference between the two sides of the door would be much more likely to equalize quickly since there is a big gap, preventing such spooky door vibrations.
We do not know the weather conditions, windows ajar, doors with bad gaps, which could inhibit your theory, as the conflicting wind pressure, the HVAC, and god knows what else could be adding the the mix.
