Lie down with me

You walk through the park during charming and nice winter evening, where you spot a young woman lying in the snow, seems to be happy. She is absolutely stunning. When you pass by, she asks you to join her. Curiously you lie down by her side and it feels pleasant. Who is she? Why is she doing this? Why she invited you? You have questions, but now you simply enjoy this beauty in the snow, who gets quite clingy and talkative.
