It's just like that sudden feeling, like being transported to somewhere, three months ago, or two years ago. When you felt a whole different way or like when you were phenomenally happy, and then that makes you miserable because you're really not that happy now, or it's back to a time when you were so sad, like, so sad, when everything was falling apart, you know? like "I don't want to be here" like "Why is this song doing this to me?" and I'm the worst person at that 'cause I lose control completely, like, we're in a pub once and I just burst in to floods of tears. And it wasn't even like, a that sad song, it was just a song that I absolutely loved. There's so many songs like that, and its just that song, and it fills inside you, and just, is overwhelming, and you suddenly think of that person, and your like "oh I miss them so much" and then its like "wait ! no I don't, I just like this song, so..." but it's hard, and horrible that a bunch of words, and a melody can make you feel like that.
