These are drawings based on subtle-knowledge of how a ghost (demon, devil, negative energy, etc.) materialising predominantly in the Absolute Water element appears when viewed through the medium of a highly developed sixth sense.
It appears whitish, transparent and flowing in a single direction. Ghosts like Jaakhin, Hadal, Witch(Chetkin), Spirit (Pishaacha) predominantly appear in this form when they materialise in a non-specific form (e.g. human-like form) in the Absolute Water element.
