   Summary

   It’s a rare occasion to see the Destroyer so small. Curled in in fetal position and snuggled in blankets, Nightmare believes these behaviors are akin to a cat. He traces the skeleton’s face gently, feeling the beginnings of a dream forming in his mind. A rare occasion indeed.

   It would be a waste to let this moment drift by without action, he muses.

   OR; Nightmare enjoys a taste of Error while he’s sleeping.

   Prompt: Somnophilia
