Corpses thought to be vampires were generally described as having a healthier appearance than expected, plump and showing little or no signs of decomposition.  In some cases, when suspected graves were opened, villagers even described the corpse as having fresh blood from a victim all over its face.  Evidence that a vampire was active in a given locality included death of cattle, sheep, relatives or neighbours. Folkloric vampires could also make their presence felt by engaging in minor poltergeist -like activity, such as hurling stones on roofs or moving household objects,  and pressing on people in their sleep. 
If monster books just aren't your thing or its pop cultural importance doesn't do it for you (check your pulse though—are you sure you're not undead?) there's still plenty more to Dracula . Stoker had lots to say about some of the most important political questions of his day. Many critics like to read Stoker's Dracula as being about the British fear that the people they had colonized and oppressed for so long would come to Britain to take revenge. Or you can read Dracula for what it says about the role of women—the most dangerous women in the novel are also the sexiest.
