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.

I'd forgotten until reading this; I had a dream involving angelic error (January, I think). It was a one of those looong days, had a headache, and after trying to do housework I gave up and took a nap.
While half-asleep, a sort of angelic figure appeared (big tough guy with a diminutive assistant). He said something along the lines of "I've finally found you after tracking you down for years since you did [something involving a bunch of dead people]." Then I got a movie of someone committing suicide and sort of disappearing, then an image of a park I went to when I was 5 (had an accident at the time place, but it's in a different county, and I haven't even been there for 4 years). So I asked why it had taken them so long to find me if this was true, the assistant said the angel guy really sucked at tracking people down, which got him mad.
The dream seemed so hokey at that point that I just laughed at them, which pissed the angel guy off even more and he just became a sort of blur, but it didn't seem to coincide with anything. So I talked with the assistant how they knew it was me and the guy refocused and they sort of argued about the evidence and it seemed boil down to me being at the same where & when that their target was. The rest is pretty vague; but they semi-apologized, left, and I woke up sans headache.
