It's called Vasovagal syncope and it is the most common cause of fainting. Vasovagal syncope occurs when your body overreacts to triggers, such as the sight of blood or extreme emotional distress. The trigger results in vasovagal syncope - a brief loss of consciousness caused by a sudden drop in your heart rate and blood pressure, which reduces blood flow to your brain.

Do vampires have blood?
Yes although it might not be the nice scarlet fluid you're familiar with. A vampire is a dead body and its blood is in a similar sorry state. Just because a vampire eats blood doesn't mean it doesn't already have some. A vampire need life-energy not blood. The fact that, for some vampires, the life-force comes with the blood is only coincidental.no! vampires don't have blood! there the people of the living dead dead people don't have blood! and plus if they did have blood don't ya think they wood may b bite themselves if they were hungry enough?!that is why they drink blood. so they can have blood in them. but it dissipates fast so they need to drink often.AnswerI don't think vampires would have the blood that we are more familiar with (scarlet and runny) because wouldn't that mean they'd tear each other apart, because if they crave blood, they'd drain themselves dry in seconds. AnswerActually since vampires are fictional characters that are written from various authors...it depends. See the related link for a website breaking down popular vampire stories and you will see most of them do have blood.
