Magic Forums

This question seems odd and as they say "fluffy" but from what I've seen in the forums that there is this thing called a "psychic vampire" or whatever I think it's called. They say that they're people who feed off the energy of others. I don't believe in vampires at all and I find this to be quite ridiculous, but from what I've seen a lot of people claimed that they are real, even when they say that the holly wood type of vampire doesn't exist. Are there actual chances that things like these exist?
