Photoreal Ghost Drifting Through a Cosmic Nebula

Photorealistic image of a translucent ghost drifting through a luminous nebula. Deep space backdrop filled with pink, purple, and electric blue gas clouds, wispy filaments, and scattered stars. The ghost is semi-transparent with a soft inner glow and barely solid edges, moving with flowing, silk-like ripples. Nebula light outlines the figure with a pale silvery halo; fine dust particles shimmer in the nebula's glow. Cinematic volumetric lighting and shallow depth of field create a sense of vast distance, while a subtle reflection of the ghost appears on the visor of a space helmet, as if viewed from inside a ship. Emphasize hyperreal detail, 8K quality, high dynamic range, and a serene yet eerie atmosphere with purple-pink-blue color grading and subtle glow around the edges.
