Mrs. Sleep only appears in Riddle School 2 where she is seen sleeping at her desk. Phil reveals that she hasn't moved since last month, giving the illusion that she's dead. But don't worry, she's not.

However, she does die by sleepwalking off a cliff, as revealed in Riddle School 4.

But, as she's not a real character, she never really existed. She was just part of Phil's dream.
