My girlfriend overdosed and Im scared advicr?

My girlfriend took 7 pills of vicodin for her pain all as t once after i told her not to and now she is acting all craz. Her eyes are getting super big and she keeps going to sleep every five minutes and waking up talking about "Good morning" like it is another day everytime she wakes up. Then she is super itchy and begging me to scratch her. When i try to talk to her she will start laughing crazy and make her eyes big. Its f***king creepy. I had to block the windows because she kept trying to jump out of them. I am worried about her and i do not know what to do advice?
