Wet grass burning

In the night time place, I'm standing in a garden looking out at wet fields all around me. Wet fields full of long wet grass. It's raining, and the grass has been flattened, and all is as wet as can be. All of a sudden, without warning, I catch a glimmer, a flicker of flame to my left, almost outside my vision. I look closer, and I know it's not really there, wet grass can't burn, yet there it is again, a burst, a glimmer of yellow. Another flicker over there, and another, then a yellow flame licks up towards the sky. Fear, disbelief, awe. Wet grass can't burn. I watch as everything turns to flame in all directions. And as everyone else in the garden runs around in blind panic, I stand before a giant canvas, and cover it in white and blue.
