the name of this piece is:
"My thoughts after midnight"
These creatures are the girl's thoughts that surround her. They are grumbling at her.
One of them looks at the clock ( it is late and you should not be awake).
Another one of them was hitting his head. The other is standing with his hands on the waist and complaining, and the other has bad news for her.
But... the girl doesn't give them any fck and eats her tea with chocolate ;))
