A Nightmare for Sandman

Dream/Morpheus/The Sandman has many nightmares. One woman who loves her job is The Void. She was initially a dream, but has fallen in love with creating nightmares around existential dread in the minds of scholars, creatives, and people who need to whip their lives into shape.

She has an important function at scaring people into thinking harder about their purpose....but honestly she mainly just likes doing it for fun
