ectoplasmic
Like spirit residue
Ectoplasmic describes something resembling or relating to ectoplasm—the viscous, luminous substance that spiritualist mediums supposedly exuded during séances, said to manifest spirits.
The word now appears mostly in fiction and games involving ghosts: ectoplasmic residue, an ectoplasmic glow.
It suggests something ghostly, gelatinous, and faintly glowing.
