Girlfriend wont stop shivering in sleep after drinking

She’s really scaring me because she’s never done this before and she keeps making random noises. I’ve wrapped her in the duvet and put a huge fluffy hoodie on her but she won’t stop

UPDATE

She’s fine and awake now. She decided to piss in my hallway as she was sleep walking. I got mad because I didn’t realize she was sleep walking and thought she just pissed in my hallway. We’re laughing about it now and she says she doesn’t remember any of the times I woke her up when she was shaking and only remembers after I sent her back to my room whilst I cleaned up her piss. At least she’s alive?
