Drawings That'll Scare the Hell Out of You - NSFW - Are You Trembling Yet?

Drawings that are scary enough to almost make you tremble are tagged with “so scary” (なにこれ怖い, nani kore kowai) on pixiv. Maybe a character is walking towards a dark corner in a blood-stained hallway. Or maybe something is lurking in the water, just below the surface… Regardless, these works are sure to send a chill down your spine.

What situation do you think is most deserving of the tag “so scary”?
