What happens to a vampire if it can't find blood?

they slowly die. it may be terrible, but its true.

Different stories/legends say different things. To some, they slowly starve and die, sometimes turning into a living skeleton (Spike says this to Giles on Buffy), sometimes turning to ash, sometimes turning to mummies (like on True Blood). Some become rabid and insane (like in Twilight). Some turn back into humans. Some lose their fangs and/or other powers.

It all varies.

thier powers start 2 slowly fade away and they soon die

In the stories I've read/seen, they become living mummies. They feel pain and agony, but can't movie.

My Buffy knowledge is blanking an this one, but I know it's true for TrueBlood and Vampire Diaries.

EDIT: true for Buffy too.

Well, my friend is a vamp, and they just start to turn human. If they dont find blood in the next hour, they die.

I guess that vamp would die

dry and then die i guess!

Personally I find it hard to believe that a vampire wouldn't be able to find blood to drink. There's billions of people on our earth and even more animals. There's always someone out there to drink from. Also I believe if they regulary drink blood, especially from healthy people, it will keep them going for a while, even if they can not hunt for a few days.

you grow weak and after a while your senses go dull. first you go blind, most go crazy, then your hearing goes below average, sense of smell goes, paralisis, pain, and then death.

i think that he would shout like anything and run faster and faster to serach a blood if naot he would see a rain deer he would kill him

It keels over and dies..then it turns into a brain-eating zombie ^.^ Just kidding, of course! (Maybe...) It most likely just grows weaker with each passing second.

There powers are slowly and after a long time they die

In the vampire stories that I've read, the vampires will usually go insane (House of Night) or they will get weaker and weaker until they eventually collapse and die (Vampire Academy). In some stories (I can't remember which ones) a vamps body will start eating itself until they eventually die of starvation, kind of like when a human can't find food. Sometimes not drinking any blood makes the vampire turn back into a human.

But I always liked the idea that the vampire's powers drain, and they get weaker and weaker and then die.
