You saw a see-through, transparent, big amoeba thing, the size of a basket ball crawling towards you, it seems that it thrives when there's oxygen, it has black veins going through all of its 6 tentacles, it works as a multicellular cell but the cells are all functioning as all things, eye-sight, nervous system, feeling, and everything, it has a lot of black veins in the middle, but doesn't have human characteristics
