I was praying over some people.
Next I was walking through a mall-like hallway and saw someone I had prayed over walking toward me. I passed by them at a specific place in the mall.
Next I was praying over different people.
Next I was walking through the same mall hallway, and saw the new people I had prayed over walking toward me. I thought to myself "wow that's strange, I'm going to pass these people in the same exact place I passed the people before - I wonder what God is doing?." Just as I was about to pass then, there was an extremely loud explosion that sent me spinning weightlessly backward. It was the loudest and most terrifying sound I have ever experienced.
When I woke up from the dream I checked outside to see if there was a bad storm with thunder, if that gives any indication to the intensity of the boom.
