I had similar feelings about other people when I stayed at the hostel in Toronto. I think it was also that the bed made a lot of squeaks so I was afraid to adjust my position for fear of waking the others...I had a miserable night...and I was tired to begin with...which is probably why I left a day early...and skipped out on lunch with people I knew. I was feeling just awful and couldn't deal with people. (I think it was also that I need my alone time, and I didn't get it that trip, because I was with strangers when I was sleeping, and the rest of the day was mostly spent doing stuff with people I'd never met in person, but knew from a mailing list.)
