depends really. how old are you ? some times after a soul reincarnates itself the mind loses touch with that particullar side "only if your a psychic vampyre " because our subconscious will take over the energy drain we require and in later years we will "reawaken to it" it also depends on how many lives you may have lived. sanguines i believe are born knowing what they are. but you would by now know if you are or else you would not have asked that question
There are two kinds of vampire. Psi's which feed on energy found in the area around them or off of people. And Sangs (sanguines) which feed off the energy found in blood. Then you have hybrids of the two like me. As crow said sangs are born knowing what they are but their need for blood energies doesnt kick in until they reach puberty. Psi's need for energy is latent at they will generally realize what they are if they experience an irresistable urge to be the centre of attention. But for the most part, Psi's wont embrace what they are roughly until maturity at age 20-25.
Also it really depends, again as crow said, how many times the vampiric soul of the person has been reincarnated. See when an awakened vampire, psi or sang, dies (yes vampires die), the soul wanders around looking for another host body. This can take weeks, years, even centuries. When it finds a suitable host, the vampiric soul will attach itself to the host. until the moment of consiousness (i.e. when the child can remember things) the soul is just a dormant entity. Then, though mature itself, it will mature again with the child until it feels the host can understand and deal with what it is. The number of times that a soul has been reborn is known at its "generation". Like me for example. I am a fourth generation hybrid of sang and psi. originaly i was bour January 18, 2752 BC in Egypt. I was Awakened in March of 2736 BC and have since been a Roman legionnaire under Julius Caeser, a sailor under Cortes, a Confederate Colonel under Lee, and now I'm a 21 year old guy from NC. So trust me you will know if your a vampire. There will be an unsattiable lust for energy when you are ready.
