Okay! So, almost everyone has an odd childhood memory of some movie, book, game, tv show, animation, website, or song- and a lot of these don’t have names attached to them. Do you have one of these things? If you do, tell us about it!

There are a lot of people here with their own experiences, so they might be able to find yours for you.

If you don’t have one, try describing something you do remember and see if anyone here knows what you’re talking about.
You might be able to help someone find theirs: if you think you recognize any of the recent posts, please reply to them! Remember: it could be the right answer!

On a larger scale, many pieces of media are lost or almost lost- one example of lost media that was then found is the Clockman, an animated short that remained almost a legend until it surfaced again, which is a good example of the kind of stuff we discuss. If you want to get into lost media, try visiting a lost media community online and reading up on some famous cases.
