Enormous Explosion Causes Worldwide Markets to Fall

[Iris]

I keep thinking about this dream. For clarification, imagine seeing a large fire at night. The red of the fire illuminates the sky. I either saw a fireball miles high, or I saw the red illumination of a huge conflagration lighting up the sky for miles up.

I was facing north and looking left, to the west.
People literally sank to their knees in despair and to pray when seeing this.

I have had many war dreams, but for whatever reason, this didn't feel like one of those; it felt more like a natural disaster.
I am trying to imagine what would cause such an event; perhaps an oil pipeline explosion, or oil or gas storage terminal explosion?
Or maybe a volcano.
Or maybe I am mistaken and this is a terrorist or war event.

Still feeling anxious and appalled by this dream.
