Two human-shaped outlines. The first is standing and labelled "awake". It is half-filled with red "anxiety" from its feet up to its waist.
The second is laying down, labelled "trying to sleep"
It is still half-filled with red anxiety, but the anxiety has behaved like liquid in a human-shaped container, and is now filling the lower leg, half the torso that's against the "ground", and half the head.
A note points out that the anxiety is in the head now.
