Some people seem to move through life without looking back very often. Others keep the cinema ticket, the birthday card, the dried flower, and the blurry photograph from a night that did not seem important until years later. A song comes on and suddenly they are 17 again. A familiar perfume brings back a person they have not spoken to in years. They rewatch the same movie because somehow it feels different when you already know how it ends. If you are an emotional person, memories can sometimes feel almost physical. And letting go of the objects attached to them can feel strangely similar to letting go of the memory itself.
There is a word for much of this: nostalgia.
Today, we associate nostalgia with old photographs and songs from our teenage years. Its history, however, is much darker. The term was introduced by Swiss physician Johannes Hofer in the 17th century to describe the intense homesickness experienced by people who were far from home. For centuries, nostalgia was treated as something closer to an illness than the bittersweet emotion we recognize today. Modern psychology sees it quite differently. Researchers including Constantine Sedikides and Tim Wildschut describe nostalgia as a sentimental longing for our own past. Importantly, nostalgia is not simply sadness. It tends to contain both happiness and loss.
You smile at the photograph because you were happy. You feel sad because you cannot return to it. Both feelings can exist at once.
This might also explain why throwing away certain objects feels disproportionately difficult. The concert wristband has almost no financial value. The screenshots could probably be deleted. You do not need 15,000 photographs on your phone. Yet these objects can function as evidence that something happened.
I was there. I knew these people. I loved this person. This version of me existed.
Research suggests that nostalgia can strengthen self-continuity, our sense that the person we were in the past is connected to the person we are today. It can also increase feelings of social connection and meaning. So perhaps we are not always collecting things. Sometimes we are collecting versions of ourselves.
For younger generations, remembering has taken on an interesting form because almost everything can now be documented. We have camera rolls, archived stories, playlists, screenshots, saved messages, and entire relationships preserved inside old conversations. At the same time, physical objects are making a curious return. Vinyl records, film cameras, and other forms of analogue technology have found new audiences among young people living otherwise highly digital lives. Recent reporting on youth trends suggests that digital fatigue and a desire for more tangible experiences may be part of that attraction. There is something fascinating about this contradiction.
We have never had more tools for preserving memories, yet we seem increasingly fascinated by ways of making memories feel tangible. Perhaps a photograph sitting inside a phone with 20,000 others feels different from one developed from a roll of film and held in your hand.
Music might be one of our strongest portals into nostalgia. Research suggests that nostalgic music can strengthen feelings of connection, meaning, optimism, and continuity between our past and present selves. This is why hearing a song you loved at sixteen is rarely just hearing a song. Films return to the same territory. Past Lives (2023) asks what happens to the people we might have become if life had unfolded differently. Aftersun (2022) shows memory as something incomplete and deeply emotional, as an adult daughter tries to understand her father through fragments of a childhood holiday. These stories resonate because nostalgia is rarely only about wanting an event back. Often, we want ourselves back.
An Existential Way of Looking at Nostalgia
Existential psychology asks us to confront realities we would often rather avoid: time passes, people change, possibilities disappear, and nothing can be kept exactly as it was. From this perspective, nostalgia makes sense.
A photograph freezes something that life refuses to freeze. A saved voice message lets someone speak again. An old T-shirt, book, or ticket can briefly collapse the distance between who we are and who we used to be.
There is nothing inherently unhealthy about this. In fact, nostalgia can help us create continuity and meaning when life changes. Research suggests that it may even help buffer existential distress. The difficulty begins when remembering becomes a substitute for living. There is a difference between visiting the past and trying to move back into it. Maybe emotional people do not need to become less sentimental. We do not have to throw away every old letter or stop listening to songs that take us somewhere else. But memories were never meant to preserve life perfectly. They remind us that something mattered. And with those memories that we cherish, we can move on, grow, and look forward to the future.
