The Doppelsauger (also known as the Dubbelsuger) is a vampire from Hannover, Germany. Doppelsauger means “doublesucker”, which refers to children who are weaned but they still continue to suck his mother’s breasts. This then causes the person to be a vampire after they die. Their lips are the only thing that remains undecayed. While they are in the grave they suck on their own breasts until there’s nothing left, then he feeds upon members of his family since they have a connection. The family members will lose weight at a rapid rate and die.

To prevent a Doppelsauger from occurring you can place a gold cross or gold coin between the corpse’s teeth or separate the head from the chest with a crescent-shaped board placed under the chin. Make sure the burial clothing is away from his mouth before he’s buried. After the funeral and the coffin is exited out the window, cover the window. He won’t be able to come back to the house, according to lore, the Doppelsauger returns to the house the same way that it left. Rebuilding and removing the window will prevent him from returning to the house. This, however, doesn’t stop the vampire from coming out of his grave. It can be stopped by digging him up and stabbing the back of his neck with a spade, it will then let out a very loud scream. After this, the attacks should cease.
