I've bought art, and hung it on the wall. It looks nice, but no matter how nice it is, it isn't long before you don't actually see it anymore.
We have a few things hanging that are nice, and they do, indeed, disappear. We also have a few that aren't as nice but where we have a connection to them. A couple travel posters as a reminder of an amazing vacation, a map of Paris where we visited and loved the experience, and a fancy triptych concert poster for a destination concert my wife attended all have meaning beyond "nice art", and I notice them at least once a week.
She treasured those, and yes, had a continuous active connection to them. Unfortunately they were all destroyed in a house fire. You can't replace those sorts of things.
