From what I've seen in movies and such. No.
You needn't worry - you're not a vampire. There is no human being alive that "has no reflection in a mirror".
A vampire / Count Dracula / Nosferatu
There are no such things as vampires they are make believe. However part of the make believe is that a vampire will nave not reflection.
A vampire is the creature that can not see their reflection because the theory is that to have a reflection you must also have a soul. Vampires do not have souls for they are dead and your soul leaves your body when you die. I therefore state Vampires will never see their reflection.
There is no "real" vampire Peter or "real" vampire of any other kind. Vampires are a fictional construct. There is not a single human being on earth who "has no reflection in a mirror".
No, vampires are fictional. They do not exist in real life - there is no one on earth who "has no reflection in a mirror".
No stupid read a vampire book for once! no Vampires actually do have a reflection. It is just that some vampires avoid mirrors because a visual confrontation as to what they have become is bothersome. It from such aversions and negative reactions to mirrors that the myth of a non-reflection has evolved. All the mirrors in Count Dracula's castle were covered but apparently this was not done by the count -- probably by one of his 'vampire brides'.
Well, he doesnt have a reflection; you see him sucking people and animals blood; he has super strength; he has cold skin; or if you feel in your soul that you have seen a vampire. -Ashton
Vampires are considered to be deviations in the popularised TV shows and films as some aspects are the same as vampire legends but many are different. For example vampires don't have a reflection in a mirror but in the film "Twilight" they do.
In vampire folklore, it is said that the undead do not cast a reflection, so if there was a mirror nearby their identity could easily be detected.
Well, isn't that just a happy little mystery! Maybe that vampire has a magical comb or maybe they just have a natural sense of style. Either way, it's always nice to see someone taking pride in their appearance, even if they can't see their reflection.
You'd only know for sure, WHEN YOU SPARKLE! If you are a vampire in the Twilight series, the above is correct. It you are a vampire in the Buffy the Vampire Slayer series, you will know by the physical transformation of you face when the "Feed" is upon you. Bram Stoker's vampires couldn't be seen in reflection (mirrors etc). My best suggestion would be to check with the author or creator of your particular brand of fictional existence for all of the details.
