Late 2000s/ Early 2010s Horror Movie?

I dont remember much of the movie but i do remember that it was a horror movie. One of the two scenes i remember consisted of a young boy laying in a hospital bed and a demon type character watching him from the corner/ceiling. I remember the demon taking a women down to a lair cave area and drowning her in a shallow well/pool that had snakes in it. I know that the boy followed them and that he was hiding behind pillars and watching from afar.

Darkness Falls (2003)?
