Honestly, I think this is something you would have to answer on your own. If it's not asking you why you think people like to connect film with other aspects of life, then the reasons should be in whatever text or lesson you had to read or listen to because there are so many reasons why people enjoy connecting film and other forms of art to their personal lives. I enjoy looking at connections between films and life simply because I love analyzing an interpreting art. I enjoy finding something I can connect to in a personal level and actually analyzing it piece by piece, learning more about the film, the symbols and themes of the film, and the people behind the film.
Hope I helped,

P.S.: Not sure if I was much help, but don't hesitate to ask for more help.
