So was he a ghost or not? The dialogue and twist seem to imply he wasn't a ghost at all. I didn't kill myself, which also means he didn't die at all. It seems to me the implication was the incident injured him in some way and her pulling at him caused him reopen his wounds. I know how unrealistic it is but the last line about her being wrong about everything reinforces the fact he was never dead to begin with, she just assumed he was. I like this one more than most.
