The song "Karma Police" by Radiohead brings me such vivid memories, it's almost painful. But I like it.

You know that feeling when you're having an adventure in a big crowd for a long period of time, around lots of people and there's lots of noise and excitement, and finally after the thing is over, you're alone and it's nighttime and you're thinking about all the stuff that just happened? That's what that song makes me feel.
