Strange visitors in the night - Drunken half naked sleepwalkers?

(entertainment factor - "High")

I heard some strange sounds in the early hours of this morning of someone stumbling up the stairs, using the bathroom and then stumbling out and then i heard screaming coming from my flatmates room! Then a CRASH, and I called out "ah is everything ok in there?" and my flatmate called out "ah no, Joy can you come here?"

So... not knowing what i'd find, i chucked on my dressing gown (ok i wasn't wearing my most suitable pjamas), and popped across the hall and opened my flatmates door to see someone lying on the floor by her bed. My flattie was sitting up in bed going "um what do i do?!" So i switched on the light and there was a girl in her mid 20's wearing only a top and our bathmat (which thankfully covered the bits we didnt' want to see - i wonder how she organised that?!) coma'd out on the floor. We could tell she was breathing so we didn't need to dial 111, but my poor flattie was a bit shaken up having a random person trying to get in bed with her and then collapsing on the floor 1/2 naked!

We woke up our other flatmate who said she was a friend of hers and was crashing the night after being out on the town. So we went back into the room and the girl had actually got into my flatmates bed! So my other flatmate got her out of the bed after about 10 mins of coercing her to get out and threatening to pick her up and carry her out of the bed!! Then I heard her say "where are your pants? go downstairs and get them!" My poor flattie was so embarassed!
