What is the name of this Christmas movie?

There's this girl who just went to the store and I think bought a sled. She later falls out of a car, she falls unconscious, but her mind goes to this land where all seems well, she meets this big guy names Georgie, and there's this small evil guy, Barnabas who lives in some sort of bowling ball. That's all I know about it. It may not be Christmas, but winter.
