ok, perfect anime for u, Koutetsu Hyaku Monogatari...insanely dark anime, with ghosts and spirits and the like, Shingetsutan Tsukihime like they said, very good also, has a vampire theme to it, but Koutetsu is far darker and freakier, for instance, in the second ep, u see a mom holding a baby, the baby is crying loudly, then something kills the mom, she drops to her knees, still holdign the baby, the baby is still crying loudly, then she falls forward onto the baby and u hear a sickening squish sound, and the baby stops crying....give it a watch, its well worth it
