Who has had hellish ndes and what were they like?

[MattMVS7]

If anyone has had a hellish near death experience, then I have two questions that I need answered:

1.) Were you in the altered horrible mental states that can only be experienced in your nightmares? They say that ndes are altered mental states and I am wondering if it's those strange/horrible mental states that you experience only in dreams and nightmares or if it was instead like your normal waking life, but only with a few features added on such as hyper reality, out of body, etc.

2.) If I were to have a horrible emotional experience in a nightmare or if I were to experience some sort of horrible mental state in that nightmare, then it would be the worst experience. But if I were to experience that same emotion or mental state in my waking life just as I did in my nightmare, then it seems that I have power over it in my conscious state to where it would not impact me like it did in my nightmares.

Perhaps there are brain regions turned on during my conscious state that allow me to have some sort of resistance against those horrible feelings and mental states. So my question here is did you have this resistance against any horrible emotional experiences or mental states during your hellish nde?

I would assume that you would since people who have ndes are more conscious than waking reality. Or did those hellish emotional experiences/mental states impact you just like a nightmare would? Or did it have an even more impact than what a nightmare would?
