Continuity: As Ben and Jane drive down the road, it is raining. After they hit the ghost, the scene fades to black. When the scene fades back in, it's heavily snowing, and a previously nonexistent thick sheet of snow is covering the ground. As they get out of the car, they start talking. During their conversation, there is a quick cut, and with this, it instantly stops snowing.
