|Occupation:||Demon of the Dream World|
By the 20th century, Superman accidentally frees him in a mining shaft in Gotham City. He and Batman were forced to fall asleep and enter the Dream World, which he seemed to have full control of at first.
As she enters the Dream World and finds the World's Finest in peril, she reminded them that dreams could be controlled through concentration. Sleep was in disbelief that they'd ever escape. However they do, and upon waking up, they put him back in his container that was imprisoning him.
