[@Prince of Seraphs] Lilly is essentially the opposite of Elizabeth.

Elizabeth: can control dreams, one person at a time, can link up dreams.
Is strongest when in dream
Induces sleep and causes fun and memorable dreams, even lucid dreams 
Can wake anyone from their dream

Lilly: can control dreams, one person at a time, can link up dreams.
Is Strongest in dream
Causes nightmares 
Can make sure they never wake

Did you just copy my powers and give them a little edit?

Xd accepted.
