Paranostalgia 

Grief over the loss of person/place/time period never experienced and (probably) romanticized.

I once came across a photo of some glamorous New Wave kids standing outside a club in 1980s London and I felt an acute sense of paranostalgia.
Sometimes I feel paranostalgic listening to my mom's old 1960s vinyl LPs.

prenostalgia

The feeling when you're doing something and realize that you will look back at this moment with nostalgia.

Bro: Man, I'm having such a good time right now, I don't wanna leave this. This is gonna be a memory one day.
You: Hey man, no prenostalgia. Live in the moment.
