Create a realistic cinematic horror sound design for a scene where a young man enters an abandoned mansion.
Start with a low ambient background drone to create tension and uneasiness.
Add the sound of an old wooden door slowly creaking open ("creeeaak...") with deep echo.
Include soft but constant wind blowing through broken windows, with occasional stronger gusts moving curtains.
Layer subtle distant echo sounds inside the mansion to give a hollow, empty feeling.
Add light, slow footsteps
