I watched this movie in 90-s, so it must be at least 1995, but considering the graphics, i'd say 1980-s.
It's about humans who are dead, so they are ghosts, and they live all together in a building. There is a lot of them, and i remember it being pretty scary, but since i was a kid it might not be. I remember the interior looking kinda elegant, and there was a greyish outside of the building. I remember loving the movie, but that is all i remember from it.
