According to Ukrainian legend, that could indicate a dual soul and the second one doesn’t die! Also watch out for the seventh son of a seventh son, a person born with a red caul (amniotic membrane covering the head), or a child born with teeth. A vampire can result if a cat or dog walks over a fresh grave, a bat flies over the corpse, or the person has died suddenly as a result of suicide or murder. Unfinished business can also cause a body to rise, as can inadequate burial rites, including a grave that is too shallow.
