Becoming a vampire...?

I know there is no suck things as vampires but, I have heard that you CAN get certain powers from drinking blood. Like improved sight and hearing and stuff. I know you wouldn't have fangs or be able to fly or any of that movie stuff, but if you drank enough blood wouldn't that sort of make you a vampire? I mean like if you slept during tha day and stuff. I guess you wouldn't REALLY be a vampire, but just from the drinking blood and having heightened senses.
