So I was thinking about how much you think the introverted sensing has to do with INTPs having bouts of sentimental and melancholic moods.
I have them plenty, the older I get and I seem to attribute songs to different people in a melancholic way. Like for my deceased grandparents and when I listen to them the emotions stirs up in me and I enjoy it. I actually enjoy the feelings of melancholia more than I enjoy feelings in the present moment.
I understand this can be universally attributed to all types but I just want the INTPs view on this.
