So biological garbage collection pauses then? skip sleep, and the brain tries to run gc cycles during runtime. Causing attention and performance latency spikes. Evolution wrote the original JVM.

Luckily it doesn’t clear all unreferenced memory, though.

Fun fact: Suppressed/hidden/lost memories due to trauma that appear to re-surface through therapy are not a real thing, as previously thought (and still by some psychotherapists). Nowadays it's understood by psychology that any memories "re-surfacing" in therapy are in fact newly created, although the patient themselves cannot tell the difference. Allegedly, whole accusations of childhood abuse may have been created out of thin air, without the victim realizing.

People can remember things that hadn’t re-entered their mind for decades. It certainly happened to me a number of times (completely trauma-unrelated and not actively elicited).

My guess is that long term memory recovery is inherently a reconstruction from the pieces that you have retained. So it is not unlikely to include dreamed up parts.

The accuracy of recollection can certainly vary, but the point is that some information is retained long-term even when it isn’t made use of in the meantime. Of course one could argue that actually it is being made use of unconsciously, but I’m skeptical of that, given the relative irrelevance of the details that can be recollected. It’s also not that difficult to imagine that some memory-representing micro-structures in the brain just happen to be stable over decades even when they remain untapped.

The debunked recovered memory therapy was something different: They would use different techniques and leading questions to try to get a patient to think they remembered something that may not have happened at all.

Some of the techniques included hypnosis or even giving the patients (including children) sedative-hypnotic drugs before pressuring them with the leading questions.

If they could eventually get the person or child to claim to have some memory of the event (after asking a lot of leading questions and maybe even drugging them) they considered it to be a recovery of the memory.

This has been my experience as someone who has experienced childhood trauma, and what I've inferred from my therapist. He taught me that the memories I have are typically exaggerations of what happened and it's hard to pin down what truly happened. The only evidence I have that has any merit is my siblings can corroborate with similar experiences since it happened to all of us, and I'm sensitive to things related to these traumas. Almost every day I can feel the things that happened, and on my worst days these areas are much more sensitive.

On top of that, I have legitimate memories that were not traumatic, but still related to the same traumas because said person attempted to encourage these activities throughout my young life on rare occasions. I didn't remember what happened as a kid, but I knew something wasn't right and I wasn't comfortable. It wasn't until I was almost 30 that I had my first "flashback" which was a fractured memory, I still remember it looked like a faded photograph in my mind, and it was accompanied by an extremely uncomfortable feeling.

The re-surfacing memories aren't real in a sense, but in my case they aren't entirely fake either.

I wonder if it's possible that things can be completely imagined with absolutely no basis what-so-ever in certain circumstances, and I also wonder how difficult it is to discern that. It seems to be a difficult concept to manage.
