(Some context here OG, the Romanian type, vampires were more like plague spreading zombie-like ghosts rather than anything we know today. They were able to take a misty form with crimson eyes and would sitting on individuals when they slept and consumed their dreams, which end up consuming their soul.
They would eat flesh feather than blood, preferably virgin women's or young children's, and they themselves looked like bloated corpses when not dream eating.
Could poison wells and small sources of natural water with a touch, calling on rat swarms to spread said plagues, their breath was toxic to the living, except vermin apparently.
And they would form naturally if you died unbaptized, an unmarried man, death by plague, or starvation. And not by turning someone into one by viral bite.
They'd typically be fended off with running water, specifically Christan holy symbols, grave dirt, garlic, certain flowers, silver, a gravedigger's shovel, holy water, or the power of prayer.)
