Ghost descending a ruined mansion staircase toward lone explorer

A film noir style image of a lone explorer standing inside a long lost forgetten mansion. A strangely beautiful but horrible ethereal ghost is floating down the stairs with her long mouth wide open and her long arms extended towards him with long, horrible claws at the end of her ghostly hands. she has an axe in her head. The air is thick with an unsettling atmosphere, hinting at untold horrors within as if something terrible happened there. Gritty realism defines the decaying facade and the overgrown, untamed landscape. Volumetric lighting filters through the dust motes, casting long, eerie shadows.
