vampires

what is this? Is it some extract from a fiction novel. IS it something so weird and real? I am sorry, I couldnt follow your words. or Could I follow the meaning of your sentences. I am really very worried, and sad about the loss of blood .. particularly, if it is something associated with pirranhas or blood sucking bats. You call them VAMPIRES.. but, my knowledge source says, vampires donot suck blood. Atleast they do not attack humans. Whatever, Please give us complete details. Wishing you SPEEDY RECOVERY.
