you stand there,feeling dizzy. in the barren wasteland of snow and ice. Your currently dreaming, or are you?

In front of you stands a tall girl with the most beautiful face and body you've ever seen, she is exactly what anyone would call a perfect girl. it's as if you knew her somewhere, yet you never did. So, who is she?

She just stands there with her hair flowing in the cold wind

Oh, who is she
