Y'know, OP, I'm in a similar boat to you. I'd like to re-watch some anime shows I haven't seen in a long time: I'm always reminding myself to sit down sometime and re-watch films, programmes and anime I loved but I rarely do it as much as I'd like. It's a shame that I haven't seen Durarara, Paranoia Agent or Serial Experiments Lain in the past 4 years.
Same goes for video games I loved playing years ago but just haven't had much time to revisit them. It's only recently I've had chance to get around to finishing the Silent Hill games again.
I guess I get a similar feeling for locations too - places I visited with my family when I was younger. Cornwall and the lake district spring to mind. I thoroughly enjoyed my time at both locations both times i visited (my most prominent memories of Cornwall are of the Eden project, the clean beaches, good ice cream, a surprising amount of sand dunes and Polperro, a great little fishing village that's filled to the brim with barrow roads and small cottages; I remember a gem and mineral shop in the lake district as well as plenty of bespoke shops that would sell handcrafted toys, gingerbread, things like that. I also remember a surprising amount of cinemas around there too). I have to revisit these places sometime.
Pic related, it's Polperro. Visiting this place as a kid and again as a mid-teen has cursed me now with a feeling of whimsy and nostalgia whenever I'm reminded of it.
