The overwhelming feeling that life was better in the past and the inescapable feeling of wanting to go back to that time.
I found an old video game I used to play with all my friends when we were kids. The nostalgia crash took up the rest of my day.

Flash Nostalgia is a sudden rush of sadness you get when you experience something (typically a song or an old picture/video) that reminds you of your past. You reminisce about the old times, good or bad, and wish you could slow down or reverse time and make better choices.
Did you hear that they played Hey Soul Sister at the assembly yesterday? haven’t heard that song since like 2010. Shit gave me flash nostalgia.

Something from the past you never knew knew existed, but realize as an adult you know everything about them.
Air Supply? Never heard of them. Oh, yeah, I recognize that song. Hey, I know all the words to this one. Wait, I know that one too. Holy crap, they also sang this one?! How do I know all the words of 11 of their songs and never knew who the hell they were?!?! That snuck up on me like a nostalgia ninja!
