djisas and Cold Storm: Thanks for the advice. I'll try to take a look at the OP as you suggest.
In the meantime, what is the darkest most frightening anime you've ever seen that I can get with eng dubs. I really didn't find D'eon or gungrave very scarey. Speed grapher was just a few instances of gratuitous gore. I don't really mind gore as long as it's only people being killed. The can be killed in the most horrible and graphic ways. I don't have a problem with that, it's just not something I have an affinity for. Otherwise, its perfectly fine. But I don't especially like it and prefer stories that use is sparingly as a way to make certain points.
I love everything dark and occult, evil and malevolent. What really gave you nightmares that fits the bill of being dark and occult? I usually find these soothing and relaxing.
I'll look into the ones you mention though. Thanks you.
