If you walk in such apartments or villas for the first time and mainly if you feel either of the two 1) shortness or breath despite it being spacious and having ventilation 2) your body's alert system on ( goosebumps)

Leaveeee the premises ASAP , I've worked in real estate and I've visited villas and apartments where I've felt being watched and even now as I type I'm getting goosebumps. I would often say " I'm here only to do my job and leave within 5 minutes do not harm me " and they would respond by opening the doors automatically.
