Spooks

She was writing on her blog. She had had quite a good idea, and was looking at it from various angles, when she found that her attention was wandering. Looking up from her desk, she saw three apparitions. They hovered, two to her right and one to her left, all of them seemingly absorbed by the words on the computer screen before them. One of them was shaking its head in a mildly disapproving manner. They were barely visible in the light of the morning. She tried to convince herself that she was imagining things because she had slept poorly. She waved her arms around and through them in case they were an exaggerated effect of dust floating in the air. They weren't. In fact, the longer she looked at them the more solid they became. Behind the increasing definition of their shoulders she saw the shadowy forms of new apparitions taking shape. She shook her head, trying to clear it, and tried to remember what she'd been thinking about before she noticed them. Oddly enough, this caused them to fade. She concentrated harder, and began to write.
