Overwhelming nostalgic sadness

I found a video on YouTube that was a compilation of commercials from the mid 90’s and it unlocked something in my where I could literally like feel myself back in time to being a 10 year old in ‘96 watching tv. I could feel my childhood home around me and smell and taste foods and things I haven’t experienced since then. Like the smell of the lobby of my local movie theater. Or the way the railing on the stairs of my elementary school felt as I descended down the stairs with my hand gliding over the rails surface. Like a flood of random sense memories. It also gave me a feeling of overwhelming sadness and loss. It was so strange because it gave me such great comfort and also such great sadness at the same time. Does anyone else have experiences like this?

Edit: link to the YouTube comp I was referring to since a few of you asked: https://youtu.be/caVQowtE350?si=IvF7TCbC3PWgoE1b

Edit 2: I fixed the link to the right video. Not sure why it posted a twenty pilot song. In my defense I was 1.5 edibles deep when I tried to post that link originally so there is no telling what I did there lol. But the link is fixed now.
