Music (writing, recording, and of course listening) Reading (H.P. Lovecraft and just about every gothic, horror, or sci-fi novel ever written)
Rob Halford, Bruce Dickinson, Dio, Ozzy, and KING DIAMOND.
Iron Maiden, Judas Priest, Mercyful Fate, Black Sabbath, and SavatageAside from these classics, I like just about every early death metal or black metal band.....rarely the newer stuff.
Poltergeist 2, Terminator 1-2, The Omen, Amityville Horror, The Exorcist, Dumb&Dumber, Monty Python and the Holy Grail, Clash of the Titans, Anchorman, and the Evil Dead trilogy are all favorites of mine.
I like watching either Comedy Central or the anime series on Adult Swim. The History Channel and Discovery Channels are entertaining as well.
Any kind of gothic or horror literature. I also like to study any occult texts, and the Necronomicon can be some fun (whether it's a fictional part or some of the truths that Lovecraft actually discovered.....I don't even want to hear or start any arguments against that...have some respect and just use your own beliefs as nothing more than a pacifier)
Heavy metal musicians and most creators of dark art. I don't have any philosophers or idealists as heroes because I can get knowledge on my own.
