I saw a ghost for the first time in game today. She came through the easel while my sim was painting. I nearly became a ghost myself. Scared me half to death. My sims usually don't die, but I had some sims I wanted to get rid of and instead of moving them out like I usually do, I just killed them out. Perhaps I should've let them live, now they will haunt Julien Cooke and his wife my model forever! (that is unless I can insim them back to life or something and just move them out).
