Still+or+Dead?

These two lines say:

They put me in the Closet – Because th ey liked me “still ” –

Whether this is referring to a real life closet, or a personal closet, like a place you can never get out of because the door is locked from the outside, we do not know. "They liked me still" is an eerie phrase, one that triggers the image of still like death, or not making a sudden movement because if you do you will face severe consequences.

What do you think it means in this context? Could it be that her parents were tired of her behavior, totally appropriate at the moment, very naturally playful? Is that reasonable to do to a child who is simply being a child?
