Using the provided image of the subject, transform the subject into a translucent, spectral ghost. Depict the spirit with an ethereal, shimmering outline, exhibiting wispy, flowing energy trails and a faint, yet visible, translucency. Place this spectral entity within an abandoned Victorian mansion, ensuring the environment conveys decaying grandeur with elements like dust-laden air, cobwebbed chandeliers, and ornate, broken furniture. The scene should be dimly lit, with dramatic natural light such as moonlight, emphasizing the eerie, melancholic atmosphere and the ghost's ephemeral form. Maintain the original pose and general proportions of the subject from the input image, rendering it entirely in a spectral state.
