I forget my own fucking birthday but let me wax poetically about extinct Australian megafauna for a few hours.

Don't forget remembering your childhood gaffes in perfect detail.

But give me a minute to set myself the mental stage and start rambling about how as a kid I was obsessed with this old faux taxidermy at the Melbourne museum because it was like a derpy wombat horse

Have you stopped by recently? Although not mammalian megafauna, they've rather expanded on the saurian section.

It's like a trance, and it's really hard to stop once you start, but you can't just pick up into it, something has to trigger the memory to surface, like seeing a certain train go past to remember specific train facts, or in my case thinking about where you I was and who I was with when I first learned some of the best facts about my thing.

At least for me personally, it doesn't work so well if I'm quizzed on the spot about it, but I do have an ongoing portion of my brain that constantly cycles through the interest, to the point where it will start leaking into everything else, or I pick up on it like a gun to an MRI machine.

Though I have AuDHD so not sure if the episodic memory is my autism or my ADHD, it feels like ADHD because the thoughts are so bouncy when they come, but it also feels like like autism because it's anxiously obsessive in a fun way inside my brain once they journey starts.

Bit of both? But it doesn't help that things like depression and anxiety can also affect memory, both of which can be comorbid with either.
