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.

Prostalgia 

(N.) The renaissance of culture and technology of the late 19th - mid 20th century, followed by "Prostalgia" or "Prostalgics". This culture movement is infused with modern day accommodations, and is based in the Baltimore, MD/Washington DC area, (which are major Hipster hot spots) and this movement is the classier brother of the hipster movement.

How to spot a prostalgic person;
What music they like, what they wear, and they're overall appearance tend to be that of your grandmother/father when they were young. These people tend to be confused with Hipsters, however, prostalgic people tend to uphold old values and ways of life, only using modern luxuries when strictly necessary. Prostalgic people also are connoisseurs of class, whereas hipsters have modern lifestyles infused with only a small bit of old world items.

Pure breakdown of prostalgic people to average people;

Avg. Person - 90% modern, 10% vintage
Hipsters - 80% modern, 15% vintage, 5% Starbucks
Prostalgics - +70% vintage, 30% modern

Here is an example of a Prostalgic being recognized at a cafe;

"Hey, is that a hipster over there at that cafe?" She asked.
"No, he's just prostalgia." He said.
"How do you know?"
"He's using a typewriter instead of a computer, see."

- Aw, I can't take all this prestalgia.

Prestalgia 

Prestalgia is a similar feeling to nostalgia. It's not for a time that's been in the past but rather in the future. You already feel nostalgic about these moments and you know that you'll be nostalgic about them long after they've passed. You can also be prestalgic about a big dream.

"Bro I feel so prestalgic about the trip to this pacific island. It will be something so special. Flying there in that small plane during sunrise, looking at the stars with my girlfriend or eating breakfast at the beach."
"Man that even gives me chills"

or

"If I'm done with university I really wanna do a trip through south america in a little VW Van. Just travelling and experiencing all these beautiful scenerys. I feel so much prestalgia thinking about that.
