It's the same thing that happens when I turn off a really good movie - one that I've lost myself to - which is that I'll be thrown back to my own reality and something hollow will settle in my chest. Sometimes, I'll watch a movie all over again just to recapture that feeling of being inside something real. Which, I know, doesn't make any sense.
