Psychology lecturer Dr Emyr William has been reported to have been carrying out an extensive research on real life blood-sucking vampires.
He said: “This is a subculture that exists in every country, especially in the West.
“They are a group of people who drink blood and drain energy from people, but their well- established laws mean they know who it can and can’t be taken from.
“Sanguine vampires receive blood from willing donors who they can only cut on certain parts of the body,and they are forbidden from taking too much.”
