This character is named Insomnia, because an encounter with her in her broken form could led to bad sleep, and trouble. As you can see, Insomnia didn't always have a monitor as a head- it fell on her, and somehow she survived, but the encounter left her with insomnia and sleep paralysis. She doesn't like her broken form- it activates whenever she remembers something from her past that is very haunting, (Usually the murder of her brother, REM.) When she's in her broken form she can't control herself, sometimes leading to her lashing out at random people.
