Murphy sleep

I turned back to Murphy, taking the plastic sack of sand out of the lunch box. I got out a piece of chalk and pushed Murphy's chair back from the desk so that I could draw a circle around us both and will it closed. It took more effort than it usually did, leaving me dizzy for a second.
I swallowed and began to gather up energy, to focus it as carefully and precisely as I could. It built slowly, while Murphy continued to inhale, and to exhale whispered screams. I put my hand on her cold fingers, and thought about all the stuff we'd been through, the bond of friendship that had grown between us. Good times and bad, Murph's heart had always been in the right place. She didn't deserve this kind of torment.
A great fury began to stir in me - not some vaporous, swiftly dissipated flash of anger, but something deeper, darker, more calm and more dangerous. Rage. Rage that this sort of thing should happen to someone as selfless and caring as Murphy. Rage that the creature had used my power, my face, to trick its way close to her and to hurt her.
From that rage came the power I needed. I gathered it up carefully and shaped it with my thoughts into the softest-edged spell I could conceive. Gently, I sent the power coursing down my arm into the grains of sand I pinched between a single fingertip. Then I slowly lifted my arm, the spell holding in a precarious balance as I sprinkled a bit of sand over each of her eyes. "Dormius, dorme," I whispered. "Murphy, dormius."
Power coursed out of me, flowed down my arm like water. I felt it fall with the grains of sand. Murphy let out a long, shivering breath, and her staring eyes began to flutter closed. Her expression slackened, from horror to deep, silent sleep, and she slumped into her chair.
I let out my breath as the spell took hold, and bowed my head, trembling. I reached out and stroked my hand over Murphy's hair. Then I composed her into something that looked a little more comfortable. "Down where there's no dreams," I whispered to her. "Just rest, Murph. I'll nail this thing for you."
With an effort of will, I smudged the circle and broke it. Then I stepped outside it, used the chalk to close it again and willed it closed around Murphy. I had to strain, this time, more than I'd ever needed to since I was barely more than a child. But the circle closed around her, sealing her in. A small haze, only an inch or two high, danced around the chalk lines, like heat waves rising from summer roads. The circle would keep out anything from the Nevernever - and the enchanted sleep would hold until the dawn came, keep her from dreaming and giving the Nightmare a way to further harm her.
