Four stories, all about ghosts in one way or another. In the third one the concept is subtle and it seems to entail a social critique, which I liked. The first one could have been even better with a somewhat different twist (e.g. the old lady being a future self of the nurse would have been cool). The second one gave my gf nightmares and I found it the most disturbing one, partly because of the imagery. The fourth one was a slow burn and the ending was ok for this type of tale.
