Nostalgia is a weird feeling. Everyone gets it every now and then, and it becomes stronger the older a person gets. Nostalgia is both a happy and sad feeling. It's a perfect example of something being bittersweet. Nostalgia is happy in the way it brings up fond memories, but it's sad in the way people realize those times are long gone, and things have changed forever. Even though many nostalgic things are stuck in the past, it's still cool to look back at some images that create nostalgic feelings.

While this feeling is personal to each individual, there are some things that trigger nostalgia for groups of people. Some toys, stores, and general vibes take people back in time. Reddit's /r/nostalgia is a subreddit where people can share photos of all the things that make them feel nostalgic. It is mainly based around '90s nostalgia, but there are photos from other times as well. Here are 28 images that might make some folks feel a little old today.
