Why do people keep talking when I'm trying to sleep!!

Two nights ago one the dorm buddies (English guy) comes home (6:30), shakes his mate untill he wakes up and desparately whispers " ... that girl, she's going to kill me"- shakes his mate again - "no seriously mate she wants to murder me, she's waiting outside!!". He seems to have complete conviction about this and given the time I assume this man is suffering from some kind of drug induced paranoia..... So I'm awake now and ask him what happened.

Basically he meets this American/Irish girl outside a famous tourist club, named Prozac, walks her back to the hostel to continue drinking with some some Aussies. The Aussies inform him ".... no seriously mate she crazy, run a mile, we're not trying to be funny here". All of sudden I remember that actually the Aussies did report a quite insane girl of this description from 2 nights prior. The story goes on that the English guy did actually runaway from her but only after she threatened to attack one of the guys with a bottle. The English guy told her to shut up and not talk like that and she replied "..oh, oh no, no don't worry , I 'm going to finish it first!". The English guy hid from her for 2 hours before returning to his room only to find her waiting outside!! ..... and she was still there 1 hour later when I let some French people in. I think the English guy was actually mostly safe but he was terrified and the girl apparently lives in Krakow but maybe she should go back home.

.... On a brighter note I leave Krakow today though I'll miss it. It was a highlight of my trip and I can recomend it to anyone, it will be a lot more expensive in a few years. Think Prague but cheaper and less tacky. Next stop Munich it'll be the longest bus trip so far, 14 hours.
