The Edge of Dreaming (2010)

Amy Hardie is a rational woman and professional filmmaker until she has a dream that her horse will die, and wakes to discover him dead in her field. She tries to pass it off as mere coincidence until another nightmare comes, in which her deceased ex-husband predicts that she will die before her next birthday. Amy chronicles her year and her quest to understand the cause, meaning and reality of her destabilizing dreams. A beautiful and haunting meditation on life and everything we hold dear.
