A person is born with the Vampire essence dormant inside their body.
Instead of being a human body with a human soul the spirit inside the body is Otherkin of some kind. Either Vampire, Were, Elvin, Therian, etc....
What happens is that at some time in your life, (often as you hit puberty, usually in your teens), the kin essence sleeping inside you begins to stir, and wake up. You become aware of seeing things differently, and often this is the time when you realise that you have always seen things a little differently, but NOW you know why! lol
This is The Awakening.
I suppose it could be seen as a kind of death, but it is more a kind of letting go. Throughout this life you will always be human on the outside, but you have to learn to let go of the limits humanity would put on you and allow yourself to feel the kin within you.
This could be seen by some as being re-born as Otherkin. But it is much more of an awakening to the real you, that has been lying dormant all the years before, awaiting the right moment.
Of course the right moment for it may not be the right moment for you. And IT does not care! lol
Unfortunately there is no way for a human to become any kind of Otherkin, there is not a single meditation/spell/enchantment or turning method that will make a human a Vampire or any other kind of kin.
Nothing in the Universe can turn you into something you are not. If you don't have it..... You don't have it.
However I do think that if the meditation went deep enough it could contact the sleeping kin-ness inside you and awaken it that way.
If you were to attempt this meditation and you were to then find you were a member of a race of Otherkin, (whatever race that might be), it would not be the meditation that caused it, it would merely have touched upon it, and awoken it.
If you have it you will eventually discover it, but do not let anyone tell you they gave it to you.... It is yours because it is your destiny and it was ALWAYS meant to be.
It is a gift from The Source, and no-one else.
