Hmm... Dark pleasures..
I appreciate this kind of subject. Each human being is an animal, who isn't? Think when you talk about it, it comes to us very often, considering the many alternative thoughts we have, and all that whole "dark side" thing inside us, the animal instinct that comes to our reactions, be them hurts, or harms, or even affection, in the best of the hypothesis... That makes us pretty much like animals, anyway. However...
Porn, food, the occult, the word "Goth" that comes to my mind many times, Gothic rock, or even metal, wolves, cause i think they're wonderful animals, just the way they are, being born to be free. The feeling of freedom... Even for doing the darkest things a human could do or think of.. The lust... The desire for sex... The anger that comes to your mind when you deal with someone or something pitiful... When someone comes to you and harms you, trying to force you into a lie, trying to make you believe you're weak, when actually you are not... He's the weak... The desire that comes to your stomach when you feel like you're needing something to digest... Hunger is the name... But sometimes you feel like it's never enough... So is it just hunger?
The night that comes, darker than any other shadow in this world, with the Moon shining in your eyes... That Great Silver Eye over there, looking at you every single night, enchanting you with its intense beauty... The heartbeat that you feel, when you approach the lips of a girl, and kiss her... All that heat and tremble in your skin, the feeling of the sweat running down your neck, the closer she comes at you... The passion... The love that you feel in a kiss... The warmth that comes to your chest, in a hug... Yeah.. Dark pleasures, or just flesh desires? We don't know until we feel it. But it's good.. Isn't it?
Vampirism? Not much, i consider myself more likely a werewolf. xD
But i still love the Night. And the Night loves me, and its chill comes to refresh me once the hot sun has been set down...
Two words to define it? I'd say: "Carpe Noctem".
