Sorry for my bad english.If you mean one must balance the spiritual and materialistic to survive i agree but it would be better if we dont have to spend our energy to mundane at all.
The reason i said darkness and not simply spirituality is because the spirituality i mention consists some hatred and aggression toward life and mundane.For example i believe love, sexuality somehow weakens human beings and hatred makes us strong and pure.As our emotions die we transcend weakness and human i think.
Since i was a child i liked horror movies, horror games etc.This was the reason i became interested in satanism and other lhp.I didnt like the perversion or raw violence but that dark feeling.When i watch a dark anime or play Baldurs Gate for example this makes me feel alive and feel darkness.In lhp darkness refers to ego or power of self as i understand, what i mean with darkness may be a little different.
I searched Gnosticism a little and liked what i see.All the better there is even satanic gnosticism.
Yeah that's interesting, most people associate the two the opposite way you have. But I have personally been thinking that both the darkness and the light pertain to both aspects yet in different ways.
But as far as the pleasure in horror movies goes. I would say that you have a connection between the limibic system, which controls aggression and fear, and the basal ganglia, which controls positive emotion and/or reward - what makes you feel good. So when you stimulate the aggression part of your brain it stimulates

If your looking at increasing spirituality, check out different forms of meditation as well. I don't particularly recomend one, because it's definitely personal preference. There's so many though, you should be able to find one you like.
Sincee you seem to like agression, you might wanna check this out too. One of my buddies at work sounds a lot like you, and this seems to help him out a lot.
