Is it true that not just anyone can become a vampire?

It seems that people may learn that but no it’s a lot more than that. Is the small fragile aura of a vampire, their low vibration. They need to suck a lot to have a fragile bigger auric field. Then their vibration is so low and so dense. Probably are born that way. A made vampire at some moment will leave those workings cause working with the source is a lot more powerful.
