I occasionally get in my head about this but it is always in the context of media. Like there is typically some media in the near future that I'm looking forward to and there is an inherent assumption that I'll get to see it. Then randomly I'll have a realization that someday that assumption won't be true and there will be some game/movie/TV show that I will know about but won't experience.
