To build from what is being talked about, in short, no you cant be “turned”.
However, depending upon what about vampires is attracting you to the idea, there are different things you can do. Using vampiric magic is something that can be learned. Taking someone’s energy and using it against them, simply pulling energy from others or other interesting kinds of magic in that area.
If you are interested in more of the astral or nonphysical kinds of work, that is also something that can be learned and taught.
Vampires like in media, are fiction. However, there are what is know as “real vampires” they tend to refer to themselves as “vampyres” or other alternative spellings. These are people who require external sources of energy to sustain themselves. They can still die, they are still human. Just humans with extra needs. Usually, there are three kinds of vampires within the living vampire community. They are psychic (energy), sanguine (blood) & sexual (specific kind of energy) vampires. In the communities that make up these groups, safety & consent are stressed within feeding for, well obvious reasons. If you have further questions, feel free to message me directly.
