Anastasia is a common name in countries where the Orthodox church (which uses Greek rather than the Latin of the Western or Roman Church) is dominant and means "resurrection," from its Greek derivation. The Greek word that came into ecclesial language for "resurrection" simply means "rise" the "...from the dead" part is only situational. Ana is making a pun on her name telling her to stay dead... which is ironic because Easter also falls at the end of the month, lol.
