Who Is Nythal? Options

I'm not sure if the question falls in this category. I dreamt I was walking through a wooded area and then two large woody arms came down from a tree and trapped me to the ground. Several stakes or large thorns also came from the tree and stabbed me in the back and I was dying. Then the tree looked at someone passing by in the distance and then it realized it was killing the wrong person. The tree's name sounded like Nythal, it was a spirit or god of some kind. It said something like 'the innocent shouldn't be forgotten' and then in compensation it revived me with extra abilities.

This is just a shot in the dark but maybe your hearing and interpretation of the word Nythal could have been somehow distorted by time and memory, and what was said might have been "Nathaniel" which means "Gift of God" or "God has given". (Hebrew)
