I like this movie. I've always wondered this.. At the beginning of the movie he sees a picture of a bunch of people who used the hotel in the older days. Then he suddenly appears in that picture as an older self. What does this mean? I've come to my own conclusions about it but I want to know if there is an actual point that I've been missing all my life.

Actually I think it was at the end of the movie when they cut to the picture..
