Bulgarians believed children born on Saturdays and died before baptisim would rise from the grave nine days after burial.
The vampire revenant would be called istral or “lost heart”. The istral preys on life stock , killing five more a night, by drianing it of blood.
Only a vampirdzhija (a vampire hunter) can kill it.

Creepy and sad.
Very sad.
I wonder how difficult it would be to convince my boss that the new guy is one of these??
First, print this out.Second, write the new guy’s name all over the margins and back. Third, put the print out in an envelope with a couple of Benjamins.Fourth, mail envelope to boss.
Sit back and enjoy knowing your boss now wonders if the new guy is and Istral or other vampire.
