There was pressure trying to crush her from all sides and preventing her from breathing in pitch black darkness.
Just as soon as the feeling started, it passed. When the pressure released her body from its unexpected grip, darkness still surrounded her. She was vaguely aware of Severus' hold on her until he pulled her closer to him roughly. He wrapped his arms around her and she leaned on him, breathing in his scent.
She was confused and had no idea where she was or why she wasn't back in her bedroom, but his embrace was too warm to resist.
