It's likely that you actually have memories about details, but don't have a way to recall these memories. I always wondered how the heck people write memories until I saw someone to do it. He used a lot of triggers – photos, newspapers, letters etc. Later I had a chance to visit museum where typical home environment of my childhood was exhibited (yes, I'm that old) and realized how many memories small things can trigger in my brain.

I agree. There are definitely triggers for old memories and I have heard cannabis also adds flexibility to that recall
