Spiritual fire

I struggled against the wire, knowing that she couldn't see it or feel it, gasping. "The window. Murph, open the window!"
She didn't hesitate for a second, but crossed the floor and threw open the window. I staggered after her, winding the frozen wire around one hand, my mind screaming with the agony of it. I fought it down, dragged it into a coil, my face twisted into a snarl as I did it. Anger surged up, hot and bright, and I reached for that power as I jerked the wire from my throat and threw it out the window as hard as I could, sending it sailing into the air.
I snarled, jabbed a finger at it, took all that anger and fear and sent it coursing out of me, toward that dark spell. "Fuego!"
Fire came to my call, roared forth from my fingertips and engulfed the wire. It writhed and then vanished in a detonation that rattled the house around me and sent me tumbling back to the floor.
I lay there for a minute, stunned, trying to get a handle on what was happening. Damn the Sight. It starts blurring the lines between what's real and what isn't. A guy would go crazy that way. Fast. Just keep it open all the time and let everything pour in and really know what everything is like. That sounded like a good idea, really. Just bask in all the beauty and horror for a while, just drink it all in and let it erase everything else, all that bother and worry about people being hurt or not being hurt -
I found myself sitting on the floor, aching from cold that had no basis in physical reality, giggling to myself in a high-pitched stream, rocking back and forth. I had to struggle to close my Sight again, and the second I did, everything seemed to settle, to become clearer. I looked up, blinking tears out of my eyes, panting. Outside, dogs were barking all over the place, and I could hear several car alarms whooping, touched off by the force of the blast.
Murphy stood over me, her eyes wide, her gun held in one hand and pointed at the door. “Jesus,” she said, softly. “Harry. What happened?”
My lips felt numb and I was freezing, all over, shaking. “Spell. S-something attacked him. L-laid a spell on him after. H-had to burn it. Fire even burns in the s-spirit world. S-sorry.”
