A disaster in dreams is any negative event that tests our beliefs and finer feelings. We do need to remember that the heightened sensations take us into areas within our psyche where we have perhaps not ventured before. Disasters such as crashing aeroplanes, falling buildings or other such images are presented to highlight extreme emotions such as fear, anger and anxiety. Many disasters in dreams echo difficulties in everyday life, pictured in such a way that they allow us to work through the problems. An exploding mine, for instance, depicts undue pressure or stress placed on an individual. You might like to consult the entries for Aeroplane, Buildings and Mines for additional clarification.
