I had a weird incident in VT2B where I saw an elderly foreigner guy just sitting on his bed with the door open, staring at the TV which was off. I think he was mentally ill. He never saw me, just stared straight ahead.
Also, I had a problem with a mentally ill lady trying to open my door each night. I asked security to pull up the CCTV tapes, but they knew who she was and said she was mentally ill and just did that all the time. I think they get a lot of older people who are nutjobs in the VT's. Not sure why. Maybe it's just the easiest place to end up if you're not real picky.
It reminded me of the single occupancy hotels I stayed at briefly when I first moved to new york city for school and was looking for a regular apartment. People can't afford climate control so you see and hear a lot of "humanity", open windows and open doors for ventilation, people in their boxer shorts, etc.
There are also a lot of single lonely people who kind of want to interact with other residents but don't really know how, or they don't just want to be in a closed door room and there are not a lot of common spaces and facilities to hang out in. Better places have pools, pool rooms, libraries, etc.
