“Reconsumption” is when you voluntarily “consume” the same experience over and over again. This obviously relates to repeating the same media [book/movie/song/etc] but it also relates to activities like going to the same place at a beach. It’s particularly common with “hedonistic” experiences, AKA fun/good/self-indulgent stuff.

So maybe you find yourself getting in a New Vegas mood every summer, or you tend to rewatch Steven Universe at the start of a new term. This kind of stuff, turns out, is actually good for you!

Why is it good? In the most general sense, it helps your mind sort itself out emotionally and it helps you become a more solid person.
