I don't know if I'd qualify as a nostalgic person under those definitions. I enjoy reminiscing about the past because I have a lot of fond memories, but this is always a positive feeling. I as well have an interest in other era's than my own and love a good trinket from another time, whether it be a film or a book or whatever.
Sometimes I also wish that I was born a decade or two earlier to experience a lot of the music I enjoy in person when the acts were at their respective peaks. But then I don't know if I'd appreciate it as much. In the moment you never appreciate something like you do in memory.
No pain or anguish for me, but a lot of reflecting at times. It might depend on how much someone is enjoying their existence now.
