You hold up a flaming hand,
running it down the back of the gown with its arms around your neck.
The garment bursts into flames
and a silent scream comes from the dead mouth within it.
The other Ghosts back off.
You set fire to a couple more as they retreat.
Unluckily they are too close and you get some burns.
Walking carefully forward you hold the rest of the Ghosts at bay
until you are safely past the woman.
