Snowglobe (2007)

A young woman discovers a Christmas-themed dreamworld inside a magical snowglobe. Angela loves Christmas more than anything. However, her family does not share her love for the holiday at all. When she is about to breakdown because of her family, she receives a snowglobe in the mail. When she opens up the snowglobe, she is transported into the world inside, where Christmas is the heart and soul for everyone who lives there. She discovers she can return to her world by going down a small path in the small forest at the edge of the village, and can return whenever she winds up the snowglobe. After a long set of visits to the globe, she accidentally gets trapped inside.
