But most have a stage of an wakening. Slowly realizing what they are and seeing things in a new light. Some fight it, others try to understand it and then acceptance. Most REAL vampires do not dress in all black and look gothic. That is mostly for role players, and wanna be's.
Most real vampires look like everybody else.
Unless one decides to tell you that they are a vampire, usually you would not know. Note that MOST true vampires are not killers, and do not go out to seek harm to others . Also note that for some this is a mental condition and nothing more. What powers do you posses, if any and what are their weakness. The Powers I posses depends on the type of vampire I am.
