I interpret it as being about a love he can’t get over, which is why he wants to eat the salt from her lost faded away lips by the tears and the pass of time and memory. And to go back to playing within logical, safe limits so no one gets hurt. To play at pretending that nothing will change. But she can read you better than you can, and she’s not good; it’s going to hurt. At that moment, he stops imagining and comes back to the present, where he sees himself poor and aging and knows he’ll never see her face again (his mind punishes him—when you’re feeling down, your mind sometimes treats you even worse). He idealizes her, feeling like she put all these doubts and suffering into his head. She makes his heart feel heavy by making him fall in love and then tearing it away.
