Apotropaics, items able to ward off revenants, are common in vampire folklore. Garlic is a common example, a branch of wild rose and hawthorn plant are said to harm vampires, and in Europe, sprinkling mustard seeds on the roof of a house was said to keep them away. Other apotropaics include sacred items, for example a crucifix, rosary, or holy water. Vampires are said to be unable to walk on consecrated ground, such as those of churches or temples, or cross running water. Although not traditionally regarded as an apotropaic, mirrors have been used to ward off vampires when placed, facing outwards, on a door (in some cultures, vampires do not have a reflection and sometimes do not cast a shadow, perhaps as a manifestation of the vampire's lack of a soul). This attribute, although not universal (the Greek vrykolakas/tympanios was capable of both reflection and shadow), was used by Bram Stoker in Dracula and has remained popular with subsequent authors and filmmakers. Some traditions also hold that a vampire cannot enter a house unless invited by the owner, although after the first invitation they can come and go as they please. Though folkloric vampires were believed to be more active at night, they were not generally considered vulnerable to sunlight.
