Sims as decor?

Thank you for your help. Ya I guess it would be creepy but...... for example , I built a hospital and uses rabbit hole rugs so that my medical Sims would use it. I would like to see a fake Sim at the desk for the patients. Maybe some sitting in the waiting room and a few lying in the hospital beds for realism. I want to build a office and school . but again I would like to have some stand ins standing by lockers ect. I once saw something like that on tumblr last year but I was scrolling and did not notice if it was Sims 4 or Sims 3.
