I didn't sleep very well last night because a really rollicking thunderstorm.

Heavy downpour with chunks. Frequent lightning.

I couldn't even count between flash and thunder. But not because they were so close together. The thunder was continuous and I mostly couldn't associate any particular rumble with any particular flash.

After about 15 minutes of continuous thunder I was moving past awe into "well, I'd really like to start relaxing soon."

Then it ended abruptly and I thought my ears had popped because it was so very quiet. I finally realized that I could actually hear my computer in the next room and wasn't deaf.  Then I heard a rumble of thunder off in the distance and began to relax because the storm was moving on.
