I have seen this movie so many times but there are a couple things I am not getting. Spoiler Is the ghost lady in the hotel room that Jack sees, supposed to be the wife of the Grady/twin girls mom, or just a random ghost? The other thing I was wonderin' was how the heck was he in the photo from 1921 July 4th ball? I mean he was alive had a wife and kid in the present (1975-ish). So was he reincarnated, possessed or something? Would love to hear your thoughts. I have read the book, but I was a kid, so long time ago and don't recall if it elaborated.
