Silver

You are sleeping.
You open your eyes in a dream. In it, you're in a snowy forest. You're in your pajamas, barefoot, but you don't feel the cold. Only a light breeze blows across you, but you don't feel cold. The snow is soft and fluffy. You could even have a snowball fight if you wanted. You can see animal tracks and human footprints in the snow: someone walked here before you.
A girl sat before you, her back to you. Her golden, curly hair fell over her shoulders. She was dressed in a long, white dress with ruffles and long sleeves. Long white wings extended from her back. They were soft and fluffy, covered in feathers. Her feet were bare, and a thin golden halo swirled on top of her head. She was kneeling with her back to you, busy in the snow. She didn't see you.

She's kind and gentle. She's afraid of people, but you've attracted her.
