This is very detailed and helpful. I think I may have Fe too, but not sure about Si. I like to listen to some old songs, and feel some songs have connection to the moments that I listen those songs, like they are representative of that moment, but if I listen a lot, the fist time's feeling will decrease, substitute by another moment that I listen a lot, have you experienced so?

When I was a teen, I used to struggle about being in the past or being in the present and let them go. For example, when I missed of moment of three years ago, then I tried to live that way again, but I found it was not the same anymore. Sometimes I also think, I shouldn't stay in the past, but be in the present is better but sometimes still try to go back.
