ghostliest
Maximally phantom-like quality
Ghostliest is the superlative of ghostly—the most spectral, ethereal, or hauntingly pale among a group: The ghostliest figure emerged from the fog last.
Like ghostly itself, the word applies to things resembling ghosts in appearance or atmosphere: It was the ghostliest silence I'd ever experienced.
