Lightning.  
Brutally shocking, burning, destroying.
A sudden flash, out of nowhere with striking speed and power.  

Then thunder.  
A rumble,
low, distant, and spine-tingling; a hovering fear, a looming threat.  
Or a crackle--
fierce, sharp, wild, unpredictable.  
A jolt.  
A deafening, heat-stopping jolt.  
Not just near you, but inside you.  
Burning in your chest, pulsing through your blood, freezing on your skin, screaming in your mind.

It ends, but it doesn't leave.  It remains, hovering in the air and burned into your soul.  It echoes.  It fades, but it remains.
