It wasn’t uncommon for Isla to sleepwalk. She had done it since she was young, always accidentally turning on the light and waking her sibling, or finding herself abruptly in the bathroom with no recollection of getting there.

It had never gone this far, though.

Waking in the middle of the night to a face at the window would be a surprise for anyone. Especially the face of a sister.

She lingered there for a long while, outside in the snow in her pajamas. Her eyes were open, but it was clear she was not conscious. As if realizing her sibling had woke, even in her sleep, she slowly turned away. She began to walk down the yard, barefoot in the snow.

The night was dark. The moon was hidden by clouds, but it was clear it was her out there, her bed lying empty across the room. She was sleep walking.
