You can title it whatever you want, but the forum section would be determined by the subject matter. If it's consensual, it would be in the BON section, but if not, it should go in the N/C section. You don't mention the type of paranormal, but if it is mostly human (ghost, vampire, some demons) it would be in the Human section (BON-Human, N/C-Human). If the paranormal doesn't resemble a human very much (werewolves in furry form, for example), then it would go in the Exotic section.
If it's going to get gory, best bet would be the Extreme section.
