Lemures was the name given by ancient Romans to their ghosts.
These ghosts would return to haunt their relatives and descendants.
They were particularly active during the month of May.
Especially around May 28.
Festivals were held to chase away the Lemure.
To drive off a Lemure drums were used as the Lemure were sensitive to noise.
Special drummers were often used going from place to place.
