I don't know if this is the right place to ask, but when I was younger, I saw a horror/thriller movie/series (I believe it was a movie?) and I've been looking for the title forever, but I just can't find it. I can't remember anything else, just a few scenes, and I would be extremely grateful if somebody could help me.

I remember a scene where the main characters were talking about a witch, which lived in a forest and the people of the village shut her up in a gigantic tree and they suspect that the time is coming when she escapes from there. If I remember correctly, there are three events that will indicate that she's going to be released, but I can only recall one: the water will turn to blood in the village.

And there was a scene, where that happened, which went like this: a little girl was playing on the streets with a doll, and the doll got thrown into a well. The girl/or the main character walked up to the well to take it out, but when it was pulled out, blood was dripping from it, because the water turned to blood in the well.

That's all I can recall, could you please help me?
