Create an image of a gothic bedroom with a grand four-poster bed draped in dark velvet curtains. The room should be dimly lit with flickering candlelight casting shadows on the ornately carved furniture and tapestries hanging from the walls. The bed should be adorned with plush black and purple pillows, and a skull-shaped candle holder should sit on the nightstand. The floor should be covered in a plush black carpet with a deep red accent rug underneath the bed. The window should have heavy black velvet drapes that hang down to the floor, and moonlight should be shining through, illuminating the room with an eerie glow.
