It depends. Some of it is more readily available in my mind than other stuff. For example, someone can bring up Christmas specials and I can think back and vaguely recall stuff like the Garfield Christmas special and other things I would watch seasonally as a child.

Other stuff is a lot deeper, and usually it is a lot harder to access because there is no straightforward path to remembering it like a holiday, because it's the things I experienced in between things like holidays.

An example I can think of of this is that I recently went through a listing of 90's television shows which were shown on the YTV network (In Canada), and I came across a couple names which vaguely rang bells; but the exciting thing was that I couldn't remember why they rang bells. One of the listings in this case it was for a show called "Stickn' Around".

Went and searched for it, found this intro sequence and suddenly unlocked the memory that I watched this show almost every day for most of my childhood, but I had forgotten because there was no correlating event that let me remember this.

(Forgive the youtube link, can't find it on invidious right now).

Makes me wonder what other lost memories I have, and how the hell I could possibly go about accessing them, because this was just by chance.

I highly recommend everyone go look up listings from the TV stations they watched in their childhood, you might just find something you forgot ever existed until now.
