Your most likely a phycological vampire. Someone who believes they are the modern interpretation of vampires (ala feeds from humans and remains nocturnal). They do not share the phycological nature of Renfield's syndrome (the phycological desire to drink blood), or the physicals attributes of those suffering from Xeroderma pigmentosum (who receive severe burns when in contact with sunlight). 
In this case it seems the vampirical delusion is corelated to attention. I believe this stems from a lack of emotional support (whether it was in adolescence, early childhood, or young adulthood). The desire to share this 'ability' works as a means of connecting to others who share the same delusion. Thus giving OP the illusion of friends.
