Dream recall extending in to the distant past

I've noticed now with increasing regularity (about 6 weeks into lucid dream training) that I will all of a sudden recall dreams that I realized I'd had a very long time ago. Years, perhaps decades. I had completely forgotten about these dreams, and I doubt I could have remembered them even if I'd tried, without all the dream recall, journaling, and immersion in dream stuff relating to inducing lucid dreams. I'm not sure for some dreams if I *ever* remembered these dreams in WL, even right after having them. Some maybe yes, some maybe no. But I without a doubt remember the experience of being in those dreams, and that they were in the past.

Does this happen to others as well? Does our brain record every dream we've ever had buried deep in long-term memory, inaccessible until an association somehow encounters it?

This has never happened to me, as far as I can remember, but I'm pretty sure that our brain record everything. A week ago I read that in a lucid dream you can ask a DC to show your forgotten dreams or a memory.

Happened to me as well somewhat, through my practice i've been recalling fragments of some dreams from years ago as well as recalled (probably) first lucid from before i've even started practicing. :)
